Kaley Cuoco posted a photo of herself in a wedding dress on Thursday, Oct. 17, igniting rumors that she and Ryan Sweeting already got married, NY Daily News reported.

According to the report, Cuoco's wedding dress photo was taken from the set of her new movie, Wedding Ringers.

 "It's my wedding day!!!! #theweddingringer #fakeweddingcalmdown," Cuoco wrote in the caption of the snapshot. As one can see in the caption, the wedding dress wasn't for a real wedding but for her on-screen nuptials.

"I caused a stir, let me tell you. A viral stir," the Big Bang Theory star told E! News.

"Well, we're shooting The Wedding Ringer...it's so funny, I've been in a wedding dress every day on this movie so I figured I'd post a picture of me in my dress because I knew it would cause a ripple effect," she continued.

"I like the dress for this character. My dress will be nothing like that. Let's put it that way," Kaley answered when asked if she liked the wedding dress. "It could be the direct opposite, if that makes any sense. But I love it for the movie, but not for me."

As for her real wedding dress, it's likely that she hasn't even gone shopping for it yet. The actress admitted that she and Ryan Sweeting are "too busy to wedding plan. In a year we will start talking about it. We are enjoying being engaged," Kaley stated

The Big Bang Theory star got engaged to pro-tennis boyfriend Ryan Sweeting on September 26 after only three months of dating.
