Christina Aguilera has moved next door to Charlie Sheen.

The 32-year-old singer has purchased a $10 million mansion in Los Angeles' posh Mulholland Estates, according to TMZ.

The website reports the residence stretches 11,000-square-feet and includes six bedrooms, eight bathrooms, a library, bar, screening room, salt water pool, spa and bathhouse, among other luxuries.

Charlie famously lives in the exclusive neighbourhood and is known for throwing parties that rage through the night at his residences.

According to RealEstalker, the Anger Management star owns three homes in the gated community.

He purchased a 8,000-square-foot property for $7.2 million in 2006 and scooped up a 9,020-square-foot abode for close to $7 million in 2011.

Earlier this month it was reported he purchased his third, a 6,625-square-foot pad that went off the market in October for $4.8 million.

Christina appears to be downsizing after selling her $13.5 million mansion in nearby Beverly Hills last year.

The singer, who shared the home with ex-husband Jordan Bratman, is believed to have made a profit on the property as she first purchased it from Ozzy Osbourne and his wife Sharon in 2008 for around $11 million.

The estate was also featured in MTV reality series The Osbournes.
