‘Modern Family’ star Sofia Vergara, who turned 40 on Monday, reportedly got quite a birthday present from her on-again, off-again boyfriend, Nick Loeb: a huge diamond engagement ring.

Vergara and Loeb, a 36-year-old Florida-based politician and businessman, broke up a couple months ago, but apparently it didn’t take. Just a few weeks later, the pair was spotted having cozy dinners together, and he went to Mexico earlier this week for her milestone birthday celebration in Mexico.

That’s when sources say Loeb proposed at the Mayan archaeological ruins of Chichen Itza, with Vergara’s friends and family as witnesses. Afterwards, the group returned to their resort hotel, where they celebrated along with Vergara’s ‘Modern Family’ castmates Jesse Tyler Ferguson, Julie Bowen and Sarah Hyland.

The star herself hasn’t publicly confirmed the happy news, but one of her pals may have accidentally let it slip when he tweeted out the above photo of Vergara at the party wearing what seems to be a ginormous diamond dazzler on her left ring finger.

The marriage would be Vergara’s second — her first union produced her 19-year-old son, Manolo. (And yes, even though the math adds up, it’s hard to believe she could have a child who’s almost old enough to legally drink.)
