That was fast! Just three weeks after she got engaged to tennis player Ryan Sweeting, Kaley Cuoco has already slipped on a wedding gown.
Relax fans, the "Big Bang Theory" actress was actually in costume for her new movie, "The Wedding Ringer."
"It's my wedding day!!!!!" she teased, posting a picture of herself wearing a lace wedding dress and veil while eating yogurt.
It was accompanied by the hashtag "#fakeweddingcalmdown."
Cuoco's real wedding to Sweeting, 27, who proposed at the end of September, won't be for a while.
"We are too busy to wedding-plan," Cuoco, 27, told reporters on the red carpet at the 2013 Veuve Clicquot Polo Classic event in October. "In a year we will start talking about it. We are enjoying being engaged."
