Audrina Patridge has revealed her 'Hills' co-star Brody Jenner is ''very happy'' with his girlfriend Avril Lavigne.

The 'Girlfriend' singer - who started dating 'The Hills' star in February after filing for divorce from her husband, Sum 41 rocker Deryck Whibley, last October - and her new lover are very settled in their relationship, according to Brody's close friend Audrina Patridge.

Audrina - who starred with him in 'The Hills' - said: "They're very happy together, they're really good together. A lovely couple."

Audrina also revealed the pop star has fitted in well within their friendship group - because she is such a "nice girl".

She exclusively told BANG Showbiz: "I first met her a couple of years ago, and thought she was such a nice girl then. She's still a really nice girl now, and is really very talented. She's so great." read more...
