Pop the champagne!

Kaley Cuoco married pro tennis player Ryan Sweeting on Tuesday night at a New Year's Eve bash at Hummingbird Nest Ranch in Southern California.

The "Big Bang Theory" starlet looked adorable in a cute, pink Vera Wang dress for the event, which was attended by Kaley's ex-boyfriend and costar Johnny Galecki.

"Greatest night of my entire life," Cuoco added on Instagram, along with the photo below.

The two have only been dating for six months, but the blonde beauty seems happier than ever!

Since announcing their engagement back in September, the actress has been gushing about her beau on Instagram, sharing their PDA-filled pictures ever since -- and even got fake married on "Ellen."
