Those famous drag-out fights that broke up Sofia Vergara and Nick Loeb? Perhaps they were about getting married. Because the glamorous couple is apparently engaged, reports UsWeekly. The Modern Family star, who turned 40 Tuesday, was surprised by her on-again boyfriend with a ring while they were vacationing at the Rosewood Mayakoba resort in Mexico.

The festive group included relatives as well as Sofia’s costars Julie Bowen and Jesse Tyler Ferguson.

An insider dished to Us that the part-time Delray Beach resident popped the question while the two were visiting the famed Chichen Itza ruins. Vergara’s pricey diamond bling is posted on her pal Fernando Fiore’s Twitter account, as reported by MSNBC’s Wonderwall.com.

This will be Vergara’s second marriage. Her first husband, Joe Gonzalez, is the father of her 20-year-old son Manolo. Loeb, whom Vergara met at a Golden Globes party in 2010, divorced Swedish wife Anna Loeb in 2009 in Palm Beach County. Vergara has been a loyal girlfriend. The Colombian bombshell was at the politician wannabe’s side as he recovered from a serious car crash in August of the year they met.

The millionaire, 37, founded all natural crispy food topping Onion Crunch. “She puts it on everything. She loves it on tomato basil soup,” Loeb told Good Day LA about his girlfriend’s eating habits in March.

Vergara, a thyroid cancer survivor, may want to have more kids. She told Parade last year that she guesses she “would do it eventually for love.” She told InStyle’s April issue that she would freeze her eggs.

Before you congratulate the couple: neither Vergara nor Loeb has yet to confirm the happy news.
