Kaley Shares Engagement Details on 'Wedding' Set

By

Kaley Cuoco shared seriously juicy details about her engagement to tennis player Ryan Sweeting with ET's Rocsi Diaz on the set of her new movie, The Wedding Ringer, and now we've got even more nuggets and the fun reactions from her co-stars, Josh Gad and Kevin Hart. Perhaps Kaley should just have her wedding right now and kill two birds with one stone?

"I'm having my real wedding here; I'm just going to do it during this scene," jokes Kaley to Rocsi on the lavish reception set at the Millennium Biltmore in downtown Los Angeles. "Because everything's set up. I just have to call [my fiancé] to come. Yes, I know, it's very odd. Life is imitating art right now. It's very, very strange."

Kaley's character is central to the story of The Wedding Ringer, with Hart as an opportunist who provides best man services for socially challenged guys, who need the traditional right-hand man on the day of their wedding and don't have one. Gad plays a groom-to-be who needs Hart's services big time – not only is he without a best man, but he's fabricated the names of nine groomsmen as well and now needs to put his money where his mouth is. Can Hart's character help pull of Gad's charade, or will it all come crashing down at the worst possible moment?
