Sofia Vergara has more than just the big 4-0 to celebrate.
The Modern Family actress -- who is currently enjoying a birthday extravaganza at a Mexico resort alongside 90 loved ones -- is now engaged to her on-again love Nick Loeb, a source confirms to Us Weekly.
Wonderwall first broke the news of Vergara's happy news and pointed out that on Monday night, Vergara showed off a tell-tale diamond sparkler in a photo posted on her friend Fernando Fiore's Twitter.
The marriage will be the Three Stooges star's second; the actress wed Joe Gonzalez as a teen, with whom she has a son, 20-year-old Manolo. (She and Gonzalez divorced in 1993).
Vergara first met the politically active Loeb (who considered a 2010 run for Florida's state senate) at a Golden Globes party in 2010; the pair split ways after "fighting for a long time" in early May, though they reunited just a few weeks later.
