Mariah Carey and Nick Cannon are selling their home in California for $12.99 million.

The couple, who have two-year-old twins, Moroccan and Monroe, put their lavish 11,750 square-foot property in Bel Air on the open market this week.

The 43-year-old singer and the 'America's Got Talent host, who got married in 2008, bought the property for $6.975 million in April 2009, according to The Real Estalker website.

The colonial style mansion features seven bedrooms, nine bathrooms, formal living and dining rooms, a state-of-the-art home theatre, games room, fitness gym, music room and a double-height half-court basketball court.

It also boasts an extra-long dark-bottomed swimming pool, open-air cabana and a putting green.

The couple also own properties on the guard-gated Windermere Island in the Bahamas as well as a three-floor apartment in New York City.

It is not yet known if they plan to buy another base in Los Angeles.

Nick, 33, recently revealed he and Mariah were drawn to each other after discovering they shared the same views and values in life.

He said: ''It was early on when I found out how spiritual she was, and we had conversations about kids and how to live life.

''For her to share these values, it instantly let me know this is the person I've always wanted.''
