Modern Family's sexiest star is off the market! Sofia Vergara is engaged to her on-again boyfriend Nick Loeb, who popped the question during a trip to Mexico for Vergara's 40th birthday. Before the actress confirmed the news, WonderWall spilled the beans by posting a recent photo of Vergara sporting a diamond sparkler. She recently told Celebuzz that she has "no plans" to marry anytime soon because she is so busy and that she is considering motherhood again. The Colombian beauty first began dating Loeb in early 2010, and they briefly split up in May 2010. This will be the second marriage for Vergara; she wed Joe Gonzalez as a teen, with whom she has a son, 20-year-old Manolo.
