The couple said "I do" at the Grand Vista hotel in Simi Valley , according to Us Weekly. Cuoco reportedly greeted guests in a red dress as they started to arrive around 4 p.m., but changed into a petal pink Vera Wang gown before the nuptials began around 10 p.m.

It has been a whirlwind romance for the "Big Bang Theory" star and her tennis pro beau, 26, who were engaged just three months after they were first spotted together over the summer.

"From day one, I just knew immediately and it's been magic. We have all the same family friends. We grew up with the same people, we just never met," Cuoco explained to Entertainment Tonight just a few days after their engagement. "So I kind of feel that I've known him my whole life. I know that it seems a little crazy on paper," she admitted. "But it's what works for us."
