Sofia Vergara's proposal caught on tape?

Right around Sofia Vergara's 40th birthday on July 10, the Web lit up with rumors that the actress and her boyfriend Nick Loeb had gotten engaged during the celebratory occasion.

Although Vergara hasn't confirmed the reports - which have also hinted that while the Emmy nominee may be wearing an eye-catching diamond, she's not actually engaged - her son Manolo claims to have caught the special moment on tape.

Manolo's already revealed that his mom has a healthy appetite on his NuevOn Web series, "Mi Vida Con Toty," and in a new installment, he captures Vergara's group trip to Mexico with friends and family.

According to Manolo, Loeb proposed to his mom at the legendary Chichen Itza.

"Then one of my mom's dreams came true. As a little girl, she always wanted to go to the top of the pyramids,” he says in the clip. “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!"

And, once they were up there, "my mother's longtime boyfriend, Nick, proposed to her," Manolo said of the 36-year-old Loeb.

But coming back down off the pyramids was reportedly a little complicated.

Vergara was apparently met by an employee of the ruins who took issue with her climb after she and Loeb strolled back down, hand in hand.

"Let me see the ring," Manolo said to his mother as she showed the jewelry off while staying mum about what exactly happened.

A rep for Vergara told People magazine that she couldn't confirm whether the actress is in fact engaged, although the magazine cites an anonymous source who says that ring was just a gift.

"It was a gift from Nick. It's a beautiful gift and a special ring but never meant to be anything more than that," the source said.
