Kaley Cuoco is planning to marry her fiancé on New Year's Eve.

'The Big Bang Theory' star is set to see in 2014 in style by marrying tennis player Ryan Sweeting on December 31 in Southern California.

A source told Us Weekly magazine the big day will be followed by a fire-and-ice-themed party with cocktails and guests dancing into the small hours.

The actress' representative first confirmed her engagement in September, just three months after the couple started dating, and a few days after they made their red-carpet debut together at a pre-Emmys party.

Speaking after Ryan popped the question, Kaley said: ''I know that it seems a little crazy on paper. But it's what works for us.''

The 27-year-old actress joked on 'The Late Late Show' With Craig Ferguson that she has been planning her wedding for 27 years and said: ''I might ride in on one of my horses, I secretly kinda want to do that.''

The blonde beauty went on a girls' getaway with her closest friends to Palm Springs in California earlier this month for her bachorlerette party.

She travelled with her sister Briana, 'Mean Girls' star Lacey Chabert and close friend Amy Davidson, among others and posed in a bride-to-be T-shirt in a photograph on Instagram.
