Obamas' White House ritual: He tucks her in at night

By Maria Puente, USA TODAY

It's funny how cute tidbits come out about the First Family when campaign season swings into full gear: People magazine is on newstands today with a glowing story on first lady Michelle Obama in which she describes how she and President Obama have to grab time alone together whenever they can.

"We have a ritual where he tucks me in, because I'm usually in bed before anybody," she says in the interview to promote her soon-to-publish book on the White House kitchen garden. "He'll come and turn the lights out and give me a kiss, and we'll talk. He's like, Ready to be tucked? I'm like, Yes I am.' "

So now we know. Elsewhere in the interview, conducted recently on the White House balcony, Mrs. O is asked, if you could be someone else, who would you be? Gamely, she answers. "I'd be Beyonce," because it looks like musicians have the most fun.

What other endearing habits does POTUS possess? He likes to sing around the house. A lot.

"Yes, oh yes. Sometimes I can't get him to stop singing," she says. "He loves it in the shower in the morning, sings to the kids. But it's not a song. He'll sing one line of something romantic or cute. Oh yes."
