Grammy-award winner Christina Aguilera has put her Beverly Hills home on the market for $13.5 million. 

The Mediterranean-style mansion -- with six bedrooms and nine bathrooms -- includes a sweeping staircase, a fanciful children's room, a gym, a game room, movie room, beauty salon and a guesthouse with a recording studio, according to the Los Angeles Times.

The property was purchased from Ozzy and Sharon Osbourne in 2007 for $11.5 million, according to public records.

Aguilera, 30, will serve as a coach on the upcoming NBC music show "The Voice," which promises to emphasize raw voice talent over style and performance. The singer told ET she's looking forward to the new job: "Honestly, this gives us an opportunity to judge them solely based on what we hear and how we're moved by their voice or the emotion in their vocal ability, and I'm thrilled to able to experience new talent in that way, which is a way I'd never seen done before."
