slipped into a wedding gown just weeks after she got engaged to tennis player Ryan Sweeting, but it wasn’t for a quickie Vegas wedding.
The Big Bang Theory
star was in character for her new movie The Wedding Ringer
when she posted a pic
on Instagram on Thursday wearing a lace dress and veil while eating yogurt.
"It's my wedding day!!!!!" she teased, followed by the hashtag, "#fakeweddingcalmdown."
Cuoco, 27, announced her engagement
at the end of September, and says she knew early on that Sweeting, 26, was The One.
"From day one I just knew immediately and it's been magic," she said
. "I know that it seems a little crazy on paper, but it's what works for us."
