Which One of Sofía Vergara's Modern Family Co-Stars Is Skipping Her Wedding to Joe Manganiello?

"I'm not sure if [the dates] are gonna match up," bride-to-be's co-star tells E! News

Sofía Vergara's upcoming wedding to Joe Manganiello is going to be quite the event.

Her Modern Family friends and family would all love to attend, but it's looking very likely that one of her ABC co-stars will not be there to see her walk down the aisle on the big day.

But who, you wonder, could bear to miss Gloria Pritchett's real-life "I do's"?  Well it's not by choice, but Nolan Gould (aka Luke Dunphy) might have no choice but to miss out on his onscreen step-grandma's special ceremony.

"I think I have something big planned around that time," the 16-year-old actor told E! News at the Elizabeth Glaser Pediatric AIDS Foundation "A Time for Heroes" event. "I'm not sure if [the dates] are gonna match up."

If Nolan's not able to make it to the Vergara-Manganiello nuptials, he'll be working on something he describes as "a little top secret." (Watch the video above to see what he has to say about that.)

And even if Sofía's onscreen nephew isn't able to make it to her wedding, we fully expect other members of her Modern Family fam to be in attendance. Julie Bowen, for example, told E! News earlier this year she was "psyched" for her co-star to marry Joe. 

Even Sofía's onscreen hubby, played by Ed O'Neill, is excited for her to tie the knot.  He confirmed his co-star's special day would be "fun," adding of Sofía, "She knows how to do it."
