Kaley Cuoco is divorcing her husband of 21 months.

The 'Big Bang Theory' star has split from her tennis player spouse Ryan Sweeting less than two years after their wedding on December 31, 2013.

A representative for the actress told PEOPLE.com: ''Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage. They ask for privacy at this time. No further statement will be issued regarding this matter.''

The 29-year-old beauty has also deleted all traces of her estranged husband on her Instagram account and unfollowed him across her various social media accounts.

While Kaley is yet to offer any official comments on the impending divorce, the comedy star did post a picture of a rather distressed looking puppy on her Instagram account and captioned it writing: ''#mood''.

The news of Kaley and Ryan's split comes just a week after the actress revealed her spouse was great friends with her ex-boyfriend and 'Big Bang Theory' co-star Johnny Galecki.

Speaking on 'Watch What Happens Live,' Kaley said: ''Well, we dated like five years ago, so I think we both moved on. Johnny is actually one of my best friends. It's a situation that ended well. I understand sometimes it doesn't. It could have gone horrible. He's one of my dearest friends and Ryan loves him. Johnny loves [Ryan]. I got lucky.''
