Avril Lavigne has sold her Bel Air mansion for $8.5 million.

The 'Complicated' singer - who bought the palatial property in 2006 with her then husband Deryck Whibley - sold the 12,184 square-foot, eight bedroom, ten bathroom home to Los Angeles Clippers basketball star Chris Paul, according to gossip website TMZ.

The home features a two-storey foyer, dual offices, a ten-car garage, a wine cellar, large gym with bath and sauna, laundry and staff quarters and a private courtyard.

The master bedroom contains a kitchenette, fireplace, patio, custom walk-in closets and dual baths.

Avril, 27, and Sum 41 star Deryck, 31 split in 2010 after four years of marriage but despite their break-up, she insists the pair will always be very close.

The former couple worked with each other on Avril's most recent album 'Goodbye Lullaby' and as well as being good friends, she still has a lot of respect for his work.

She said: "I have a lot of respect for him as an artist. He's one of the most talented people I know. He did an awesome job on my album.

"We're very good friends. He's family to me. We both respect and care for each other very much. We're in a great place."

Avril is currently dating reality TV star Brody Jenner.
