Kaley Cuoco and Ryan Sweeting got engaged after only three months of dating and it looks like the Big Bang Theory star is just as eager to partake in all of the fun pre-wedding activities as soon as possible. After celebrating her bachelorette party in Palm Springs, Calif. last weekend, Cuoco, 27, had a star-studded bridal shower on Saturday.

Though her friends called it a "pre-holiday party" on Instagram, the dressy brunch was in honor of Cuoco's impending nuptials with tennis star Ryan Sweeting. 

Celebs in attendance included TV personality Ali Fedotowsky, "Mean Girls" star Lacey Chabert, and "Big Bang Theory" costar Melissa Rauch. The blond bombshell's younger sister, Briana Cuoco, who recently appeared on "The Voice," was also in attendance, posing for pictures with her A-List sis and her friends.
