Lady GaGa has splashed out $24 million on a new mansion.

The 28-year-old singer - who grew up in New York City - has reportedly purchased her first home in California.

A real estate source told gossip website TMZ.com that the 'Bad Romance' hitmaker bought a huge compound in Malibu from the founder of Warner Bros Worldwide Consumer Products Division, Dan Romanelli.

The lavish property, which has a secret entranceway, sits on six acres and boasts five bedrooms, 12 bathrooms, an elevator, pool, gym, wine cellar, two-lane bowling alley, bocce ball court, eight-horse stable and walk-in closets.

Romanelli put the house on the market for $24.95 million in May 2013.

The blonde beauty previously insisted she would never buy a house in Los Angeles after sampling the lifestyle there in 2011.

She said at the time: ''I ran furiously back to New York, to my old apartment, and I hung out with my friends, and I went to the same bars.''

The Grammy Award winner - who is dating 33-year-old actor Taylor Kinney - started renting a luxurious penthouse apartment in New York City last year for $22,000 a month.

The 'Applause' hitmaker has an estimated net worth of $220 million, according to Forbes magazine, and also invested in a property in the plush Fitzrovia Area in London in 2012.
