Kaley Cuoco's new husband thought their wedding was the ''best night in history.''

'The Big Bang Theory' star tied the knot with Ryan Sweeting on New Year's Eve (31.12.13) at the Hummingbird Nest Ranch in Southern California, and the professional tennis star has admitted it was a ''magical'' occasion.

The 26-year-old groom shared a picture of them kissing after they exchanged vows on Instagram with the caption: ''My cheeks hurt from smiling so hard. Best night in history.''

He later posted another image of them walking down the aisle together, with the caption: ''Says it all. Magical.''

Kaley, 28, also shared pictures of their ceremony with her Instagram followers yesterday (01.01.14) and echoed Ryan's sentiments.

She wrote: ''Greatest night of my entire life. Last night I married my sweetheart. Life couldn't be sweeter.''

The actress wore a petal pink Vera Wang gown for the event.

The couple celebrated with their 150 guests, including Kaley's co-star and ex-boyfriend, Johnny Galecki, at a fire and ice-themed reception.

The blonde beauty, who got engaged to Ryan in September after just three months of dating, previously claimed she instantly knew she wanted to marry him.

She said: ''From day one, I just knew immediately, and it's been magic. I kind of feel like I've known him my whole life.''
