Newly engaged actress Kaley Cuoco might not have jumped the broom with her fiance' Ryan Sweeting yet, but she sure did give fans a tease Wednesday. 

She shared a pic of herself in a wedding dress on her alter ego, Norman Cook's Instagram page and captioned it, "it's my wedding day!!!! #theweddingringer #fakeweddingcalmdown."

Cuoco appears to be on the set of her newest flick The Wedding Ringer also starring funny guys Kevin Hart (who gives "best man services to socially challenged guys, who--for whatever reason-- have no one close enough to agree to stand by them on the day of their wedding," according to a synopsis.

In the photo the Big Bang Theory star is chowing down strawberry yogurt. It got more than 20 thousand likes and several fans commented. 

One said, "LOL!!! Can't wait to see the movie!" 

Another replied, "The most beautiful fake bride ever! Love ya"

We previously reported that Cuoco's real-life fiance and tennis player Sweeting popped the question after three months of dating on Sept. 25.

She and Sweeting are in no rush to tie the knot, according to US Weekly. 

"We are too busy to wedding plan. In a year we will start talking about it. We are enjoying being engaged.

In an interview with Entertainment Tonight that aired on Sept. 30, she admitted, "From day one I just knew immediately. It's been magic. We have all the same friends and grew up with the same people we just never met. I know it seems a little crazy on paper but it works for us."
