Kelly Cuoco surprised Big Bang Theory fans by sharing a photo of her in a wedding dress.
Dressed in a long, white lace dress and donning a veil for the Instagram pic, Cuoco is seen sitting in a chair eating what appears to be an ice cream sundae.
But the engaged Big Bang Theory star was just playing a joke with her fans.
"It's my wedding day!!!! #theweddingringer #fakeweddingcalmdown," Cuoco's photo caption reads.
Cuoco announced she is engaged to tennis star Ryan Sweeting in September after dating for three months. The couple made their first official public appearance at the Emmy Awards Sept. 22.Follow @JamShowbiz
