Prime Minister Justin Trudeau's arrival at the White House sparked a flurry of activity on Twitter, as Americans reacted to the PM and his friendly encounter with U.S. President Barack Obama. 
  
 The two leaders appeared happy and at ease when they appeared on the White House lawn Thursday morning. Obama casually joked about Canada-U.S. differences in his welcoming speech, saying there are some things the two nations will never agree on, such as "whose beer is better," and "who's better at hockey." 
  
 "Don't get me started," Trudeau said as he stood beside Obama. 
  
 "Where's the Stanley Cup right now?" Obama fired back. "I'm sorry, is it in my hometown right now, with the Chicago Blackhawks?" 
  
 When his turn came at the podium, Trudeau ad-libbed a joke of his own, saying that Americans enjoy many exports from Canada, "including Jonathan Toews, Duncan Keith and Patrick Sharp of the Chicago Blackhawks." 
  
 As a few hockey fans were quick to point out on Twitter, however, Trudeau misspoke in that Sharp is no longer a member of the Blackhawks. He was on Chicago's Stanley Cup-winning team last year, but was traded to the Dallas Stars last summer. 
  
 Obama remarked during his speech that he's "never seen so many Americans excited by a visit from a Canadian prime minister." 
  
 As Trudeau delivered his opening remarks, some on Twitter said they had crushes on Canada's "hot" PM, while others declared the fledgling Trudeau-Obama relationship a "bromance" in the making.

 First lady Michelle Obama and Sophie Gregoire Trudeau had some fun of their own later in the morning, at a press conference for Obama's Let Girls Learn charitable initiative. Obama said Gregoire Trudeau was like her "soulmate," and joked that "we're going to be in a lot of trouble before this visit is over." 
  
 Obama praised Gregoire Trudeau for having a "great sense of humour," and described the youngest Trudeau boy, Hadrien, as "the delicious one" with "lots of curly hair." 
  
 "Pudgy. You can say pudgy," Gregoire Trudeau added. 
  
 It wasn't the only bit of attention Hadrien garnered on the trip. ||||| President Barack Obama and Prime Minister Justin Trudeau may be having a bromance, but now their spouses are "soulmates."

 Ms. Obama introduced Ms. Grégoire-Trudeau as "my soulmate right now." 
  
 "We've already gotten into trouble," she joked. 
  
 The first lady praised the Prime Minister's wife as a funny, beautiful role model who is a wonderful mother of three kids, including one "delicious" one, referring to youngest son Hadrien's curly hair. 
  
 "Sophie's a very passionate advocate for women and girls," Ms. Obama said, as Ms. Grégoire-Trudeau looked on. 
  
 While their husbands were in the Oval Office, their spouses attended the Let Girls Learn event at the United States Institute for Peace, before meeting up for a luncheon at the State Department hosted by Secretary of State John Kerry. 
  
 The Let Girls Learn program seeks to empower girls around the world, funding projects that help young women get an education. Ms. Obama said 62 million girls around the world are not in school. 
  
 "Canada truly understands that gender equality and gender empowerment is a priority," Ms. Grégoire-Trudeau told the crowd, made up of special visitors, Girl Scouts and members of Girls Inc., a non-profit organization.

 She told the audience that they are the leaders not of tomorrow – but of today. 
  
 "You be fearless, because you already are fearless," she said. 
  
 The two women were greeted by students in the French-immersion program at Virginia's Kent Gardens Elementary School, who serenaded them with French songs before the event. 
  
 "It almost feels like home," Ms. Grégoire-Trudeau said. 
  
 Liberal MP Celina Caesar-Chavannes, who was in the crowd, said it's important for Ms. Grégoire-Trudeau to play an active role in the public eye. 
  
 "She has a role to play in our democracy, and I'm very glad that she's out there and she's being more present, and more accessible," Ms. Caesar-Chavannes said.

 "I think that when young girls see that, and young women see that, they are inspired to do bigger and better and dream beyond what they possibly could dream about." 
  
 The Prime Minister's Office also revealed the gifts the Trudeaus gave to the Obamas: a sculpture for the President from Cree artist Leo Arcand, from Alexander First Nation in Northern Alberta, and an aboriginal beaded cape from Tammy Beauvais, a fourth-generation artist from Kahnawake, Que., for Ms. Obama.

 Obama laid out a full military band and ceremonial guard on the South Lawn, making the recently elected prime minister the first Canadian leader in 20 years to receive an official-level visit. 
  
 After talks in the Oval Office and a Rose Garden press conference, Obama will host a state dinner, with guests that including Mike Myers, Ryan Reynolds, Michael J. Fox and Blake Lively. 
  
 The 54-year-old Obama has saluted Trudeau, 44, as political and generational kin, an ideological colleague who shares a belief in the importance of issues like healthcare, gay rights and tackling climate change. 
  
 "He campaigned on a message of hope and of change," said Obama, echoing his own 2008 campaign message. "From my perspective, what's not to like." 
  
 "Justin's talent and concern for the Canadian people, and his appreciation of the vital role that Canada can play in the larger world is self-apparent."

 Obama's effusive praise was met with an invitation to visit Ottawa later this summer and address the Canadian parliament. 
  
 "That's a great honor," said Obama. "I look forward to the opportunity to speak directly to the Canadian people about the extraordinary future that we can build together." 
  
 In comments that were perhaps directed at Canadians who feel slightly ignored by their larger neighbor, Obama said the visit reflected "something we Americans don't always say enough, and that is how much we value our great alliance and partnership with our friends up north." 
  
 Trudeau also reciprocated Obama's compliments, describing him as a "man of both tremendous heart and tremendous intellect."

 There was also some jovial ribbing, with Obama joking about national rivalries over whose beer is best and Canada's national obsession, ice hockey. 
  
 "Where's the Stanley Cup right now?" Obama teased. "I'm sorry, is it in my hometown with the Chicago Blackhawks?" 
  
 Trudeau hit back that the team's trio of superstars -- Patrick Sharp, Jonathan Toews and Duncan Keith -- were among Canada's greatest exports. 
  
 "There is no relationship in the entire world like the Canada-US relationship," he said. 
  
 Early on Thursday, the White House announced that Canada had agreed to match an existing US target of reducing methane emissions by 40-45 percent below 2012 levels by 2025 from the oil and gas sector.

 The two countries also agreed on measures to better manage the Arctic wilderness, creating low-impact shipping corridors and managing fish stocks. 
  
 During former prime minister Stephen Harper's long tenure, the environment had been a serious point of contention with Washington. 
  
 Harper had argued forcefully for building a new trans-border pipeline to carry Canadian crude through the United States, a plan that Obama ultimately vetoed. 
  
 Obama and Trudeau met as their country's leaders for the first time at an Asia Pacific Economic Cooperation summit in Manila in November, a month after the Canadian won a general election. 
  
 Trudeau has refused to reconsider a campaign promise to pull Canadian jets out of Iraq and Syria. 
  
 But the two men put aside differences over Syria and the fight against the Islamic State group to joke about graying hair and trade compliments about their spouses and kids. 
  
 The warmth of the encounter triggered a flood of online jokes and tongue-in-cheek reports on a budding "bromance" between the leaders, as photos went viral showing them smiling like old buddies, or cooing over a photogenic baby on the South Lawn. |||||
Canadian Prime Minister Justin Trudeau's state visit to Washington went so smoothly that social media and even the press seem agreed that a "bromance" has bloomed. In the first such visit since Jean Chretien dined with Bill Clinton at the White House in 1997, Trudeau and President Obama discussed issues including terrorism and climate change and appeared so much in sync that the Washington Post, AFP, and the New York Times, among many others, used that bromance descriptor. It was also big on Twitter, notes CTV. Meanwhile, Canada's Globe and Mail notes that Michelle Obama introduced Sophie Grégoire-Trudeau as her "soulmate" when the spouses attended an event to promote girls' education Thursday morning. The two countries are "closer than friends," Trudeau said at the Thursday night state dinner, which was peppered with Canadian celebrities, including Ryan Reynolds and Michael J. Fox, the Post reports. "We're more like siblings, really," he said. "We have shared heritage, though we took different paths in our later years. We became the stay-at-home type. You grew to be a little more rebellious." Obama praised the "enormous energy" of the Canadian delegation and warned the new leader: "If in fact you plan to keep your dark hair, then you have to start dying it early. You hit a certain point, it's too late. You'll be caught." McClatchy notes that Trudeau would be wise to push for a close relationship with the Obama administration now, as bromance is unlikely to blossom between the liberal leader and the likes of Donald Trump or Ted Cruz.
