PHOTOS Modern Family’s Sofia Vergara, 41, stuns in thong bikini

Modern Family‘s Sofia Vergara let fans know there’s almost a full moon down in Mexico!

In a picture posted to her WhoSay, Sofia stunned in a thong bikini.

“Nothing like Mexico!!” the 41-year-old actress boasted in the caption for the picture of her and fiance Nick Loeb.

The couple has been down in Mexico for a holiday getaway with friends and family for the past few days. Activities included a birthday dinner for Sofia’s mom and plenty of time on the beach.

In the new year, Sofia will rejoin the cast of Modern Family. On the show, she plays a second-time mother to a baby boy. In real life, Sofia — who had a son when she was 19 — and Nick hope to expand their family soon with the help of a surrogate.

“I will have to use a surrogate, because I had thyroid cancer and lots of radiation,” Sofia said last spring. “I don’t want to wait forever.”
