Sofia Vergara's son has confirmed her engagement.

The Colombian actress is planning to tie the knot to her on/off boyfriend of two years, Nick Loeb, after he proposed to her during a recent vacation to visit Mayan ruins in Mexico. "As a little girl, she always wanted to go to the top of the pyramids. Unfortunately, people are not allowed to do that anymore. But since it was her birthday, her team worked for months on end to get her special permission to go up! Once they were to the top of the pyramid, my mother's long-time boyfriend, Nick, proposed to her, " her 19-year-old son Manolo, 19, revealed in his video diary.

In the video (seen after the jump), Sofia is seen walking down from the pyramid with a huge ring on her finger. However, as she returned from the top of the pyramid, the romantic moment was spoiled slightly by an over-zealous security guard, who shouted, "We have evidence you went up! Just surrender yourself voluntarily. We have proof!"

Thankfully, Sofia's guide was on hand to explain the situation, and she and Nick were allowed to continue along their way. Manolo - Sofia's son from her marriage to Joe Gonzalez - then told how the party went for a traditional meal to celebrate, and Sofia's aunt Gloria led the family in a spot of traditional dancing on a specially erected stage.
