'The Big Bang Theory' actress split from her tennis player husband Ryan Sweeting in September 2015 after less than two years of marriage.

But as she rebuilds her life following the marriage breakdown, the 30-year-old star's sister Briana said she is coping extremely well.

Briana said: "Kaley's never been better. She's good. She's so happy."

Having a close sibling has been helpful for Kaley, with Briana admitting her sister has turned to her for support as she comes to terms with the split.

She added to Entertainment Tonight: "Everyone goes through hard times and as long as you're there for that person and they know you're going to be there without judgment and you can be just a good sounding board, that's all you can do for someone."

Kaley's in no rush to find a new boyfriend, but Briana has already thought about the kind of man she'd like to see her sister with.

She continued: "She has a really great sense of humour so someone who makes her laugh and makes her feel comfortable and confident in what she's made for herself in her life."

But the most important thing, Briana added, is that he's "not a jerk!"
