The couple who have been on and off for four years celebrated Vergara's brithday and their engagement in Mexico with 90 pals that include Modern Family co-stars and of course Vergara's son, Monolo.

The couple broke up in May for several weeks after a series of arguments and Vergara was spotted out partying often following the split. However, the couple reconciled and is now heading for the altar.

We wish the happy couple a lot of luck!
