WATCH: Joe Manganiello Is 'Very Protective' of Fiancee Sofia Vergara
While Zunino is a wedding dress designer, two sources confirm to ET that he won’t be the one designing Vergara’s wedding gown, which will be by Zuhair Murad. Instead, Zunino is designing one of Vergara’s reception dresses and will be working on gowns for her for the upcoming awards season.
Less than a week ago, Zunino posted a candid photo on Instagram with Vergara, teasing exciting times ahead with the 42-year-old star.
“Stay tuned to see what we're making for my friend Sofia!! A little something special for a very special day!!!” Zunino captioned the pic.
Wedding prep has been ramping up, as Vergara and Manganiello are set to walk down the aisle in less than two weeks in Florida.

“I’m very protective,” Manganiello told ET earlier this year. “There’s times when paparazzi can be very unruly and very inappropriate and very intrusive.”
"I was a bouncer and a bodyguard all the way through college and then into living in L.A. for a little while, and I go into that mode," he continued. "So everyone will wind up loving her, and they'll hate me, because I'm protecting her."
