Kaley Cuoco has taken her husband's Ryan Sweeting's surname after tying the knot.

The 'Big Bang Theory' star and her tennis player beau got married at the Hummingbird Nest Ranch in Southern California on New Year's Eve (31.12.13) and she has now changed her name on Twitter to Kaley Cuoco Sweeting.

A video of the 28-year-old star getting ready on her big day was also uploaded onto YouTube today (07.01.14) by her make-up artist, Jamie Greenberg.

In the video, the blonde actress says: ''We're here for a very special day. It's New Year's Eve and I'm throwing a big, big party, I can't wait. But, there's one special thing that might happen tonight: I'm getting married!''

Once dressed for her ceremony, she exclaimed: ''I feel unbelievable. This is my custom gown by Vera Wang; I wanted to wear pink. I can't wait to go get married to Ryan.

''I'm not nervous at all. I've never been less nervous in my entire life.''

The couple appear to be enjoying married life but Ryan, 26, has been feeling the pressure of the media attention and wanted to set the record straight on Twitter after it was reported Kaley had bought him a BMW.

He posted: ''As sweet as my new wife is, I can buy my own car you effing idiots. P.S stop following us everywhere we go to get the exact same picture. (sic)''
