Actress Kaley Cuoco and tennis star Ryan Sweeting are reportedly planning to tie the knot on New Year's Eve.

"The Big Bang Theory" star, 27, and the athlete got engaged in September after just three months of dating. Over the weekend, friends and family threw Cuoco a bridal shower.

Last week, the actress held a mini getaway with her closest friends in Palm Springs. She invited sister Briana, actress Lacey Chabert and close friend Amy Davidson, among others to the bachelorette-like party.

According to, the couple plan on getting married on Dec. 31. The ceremony will reportedly take place in Southern California, and the reception will feature a "fire and ice" theme.

Cuoco recently revealed she wants a dog-shaped wedding cake because she's obsessed with animals: "The whole farm's gonna be at our wedding. I'm a big animal freak. I'd rather have the animals there than real people."

She added, "I might ride in on one of my horses. I secretly kind of want to do that."
