Avril LavigneAvril LavigneRock chick Avril Lavigne has splashed out on a new pad.

It's a mansion that boasts eight bedrooms and more than ten bathrooms.

The three-story, 12,000 square foot house is located in the posh LA neighbourhood of Bel-Air, the Los Angeles Times reports.

Avril and her hubby, Sum 41 frontman Deryck Whibley, have reportedly paid £4.8 million for the home.

The mansion also boasts an elevator, a sauna and spa, a pool, and garage space for 10 cars.

Estate agent Arnold Horland - whose wife Eva sold the home to Avril and Deryck - told People magazine: "She had to have it."

The house was previously owned by another rock star couple - drummer Travis Barker and his wife, Shanna Moakler.
