The Big Bang Theory star, 28, posted an Instagram photo Wednesday of herself in a pink Vera Wang gown, kissing the tennis pro, her beau of six months.
The caption: "Yep :) #thesweetings."
The couple wed at Hummingbird Nest Ranch in Santa Susana, Calif., in front of about 150 guests.
Cuoco's unique gown was a Vera Wang creation, the designer confirmed in a press release Wednesday. Cuoco said "I do" in a petal pink strapless tulle ball gown with sweetheart neckline, hand gathering detailed bodice and hand appliqué Chantilly lace accents.
After the ceremony, she changed into a short red dress.
It was a whirlwind romance for the star and her beau, 26, who were engaged just three months after they were first spotted together.
But friends say this couple is meant to be. "Ryan is such a good guy," says a Cuoco pal. "They make each other so happy."
Said the actress in September: "I know that it seems a little crazy on paper but it works for us … From day one, I just knew immediately and it's been magic."
