Is this Kaley Cuoco's wedding dress?!

The "Big Bang Theory" star posted a photo of her donning in one gorgeous gown to her Instagram page on Thursday. 

But before we get all worked up, the 27-year-old actress won't be wearing this down any real aisle anytime soon. Kaley wrote,  "It's my wedding day!!!! #theweddingringer #fakeweddingcalmdown," along with the funny photo. 

While this look is just a costume for her upcoming movie, "The Wedding Ringer," wedding bells are definitely in the blonde beauty's future. 

Kaley and her latest beau, Ryan Sweeting, recently got engaged. Her rep confirmed the news to toofab in September. The actress and her pro tennis player fiance had only been dating for three months when he proposed. 

Cuoco has since said that the two plan to have a long engagement, and she's not even going to start thinking about planning a wedding until next year.

Either way, she looks good in that dress!
