Sofia Vergara and Joe Manganiello know when they’re getting married. The Modern Family star admits her wedding date is set. Unfortunately she isn’t divulging any details–either to her fans or her costars.

It was at Paleyfest 2015 on Sunday where Sofia Vergara was promoting Modern Family that she dished–sort of–about her wedding date.

E! News asked Sofia how her wedding planning is going.

“It’s going,” she said.

“You know it takes time,” she added. “It’s gonna be something very important for me, so we’re trying to do it right.”

So what about that wedding date?

“Oh yeah, we knew since the beginning what date,” she told E! News.

But she didn’t tell them when.

Even Sofia Vergara’s costar Julie Bowen is clueless when it comes to wedding details. She appeared on The Ellen DeGeneres Show recently and chatted about the impending nuptials.

“I like to lie about it,” she explained. “People always ask and I think it would be fun if we had a clue, but I don’t know if she has a clue…They’re either gonna run away and elope or it’s gonna be 1,000 people.”

Alas, no one is any closer to knowing when Sofia Vergara and Joe Manganiello will tie that proverbial knot.

The couple is working on starting their family, however. They’ve reportedly found a surrogate to help them bring a baby into the world.
