Stunning Sofia Vergara turned 40 on Tuesday, though her birthday celebration has lasted for days!

While everyone is buzzing about that new rock she's sporting on her finger -- is it an engagement ring?! -- the "Modern Family" beauty has been partying it up with 108 of her closest family and friends in Mexico!

NuevOn, the Hispanic pop culture YouTube channel, sent their cameras along for the fiesta, with Sofia's 20-year-old son Manolo Gonzalez (yes, she really has a son named Manny!) narrating the craziness.

Check out the footage above, including the chartered 737 filled with party-goers boozing it up and playing the accordion; meet Sofia's ex-husband Joe -- Manolo's father -- who was the DJ for the celebration; and see the "Modern Family" cast with Sofia's Aunt Gloria, who is allegedly the inspiration for the Gloria we know and love on the show!

Engaged or not, we have to say, Sofia knows how to throw a party! Feliz cumpleaños!
