Kaley Cuoco is officially married.

The Big Bang Theory star wed her fiancée of three months, tennis pro Ryan Sweeting, in a fire-and-ice themed New Year's Eve bash at the Hummingbird Nest Ranch in Santa Susana, Calif.

Donning a pink strapless gown, the 28-year-old actress and 26-year-old athlete spared no expense on their big day, according to The Daily Mail. Their 150 guests were entertained by fire-breathing entertainers and others on stilts in a large white marquee placed on the ranch's property to ensure privacy.

After the ceremony Cuoco changed into a plunging red dress that had short sleeves and an above-the-knee hem. As part of the wedding's theme, women were required to wear either red or white. Men were required to wear red or white ties.

Earlier in the day, Cuoco and her bridal party were spotted at the ranch wearing pink T-shirts that appeared to feature a photo of her sister Briana, who briefly competed on NBC's The Voice last year.

Cuoco later shared a photo of herself with her new husband on Instagram. Sitting on the floor with her dress pooled around her, she and Sweeting shared a kiss.

"yep. #thesweetings. @ryansweething," she captioned the pic.

Cuoco began dating Sweeting in June 2013 after a brief relationship with Man of Steel star Henry Cavill ended. The two made their first public appearance as a couple at the Primetime Emmys in September and announced their engagement a few days later.

She previously dated her Big Bang co-star Johnny Galecki for two years, though the couple kept the relationship secret until after they had broken up.
