EXCLUSIVE: Sofia Vergara Wears Curve-Hugging Mark Zunino Dress for Cocktail Reception

She knew she wanted gold, I talked her into shades of rose gold, gold and bronze," Zunino shared exclusively with ET. "She also trusted me to make a custom skin tight corset, making sure everything would stay inside the bustier while she was shaking her butt! What she didn't realize was how heavy the crystal beads weigh. The bustier's total weight was 25lbs and when you're dancing around, that's a lot of weight to manage, especially when she's as petite as she is. She definitely worked her magic"

"I'm talking Caribbean Queen you a bronze Jamaican / and Colombians you guessed it in Queens," Pitbull rapped while Joe Manganiello's new bride showed off her best moves. "She's fine, that's something you've never seen / She's fine like something straight out of a magazine / She's fine like Sofía Vergara."

The Colombian beauty shared a sneak peek of her dance rehearsals with Pitbull just a few hours before the show on her Instagram with a sassy slow-motion video.

This isn't the first time that Pitbull and the 43-year-old actress have shared a dance. Pitbull performed a high-energy version of "Fireball" at Sofia and Joe's wedding reception back in November.
