Britney Spears' impulsiveness isn't confined to head-shaving and taking impromptu dips in the sea in her underwear - it also extends to house hunting.

The singer was so impressed with Ray Liotta�s Pacific Palisades mansion that she snapped it up after a whirlwind 40-minute viewing.

Britney made sure that the house met her stringent requirements � by taking a dip in the pool with her sons, having a bath and testing all the toilets � before dropping �4 million on the Goodfellas star�s Mediterranean-style home.

An insider tells the Daily Star: �Britney has spent the past month looking for a new pad ever since the child protection services reported that her Malibu and Bel Air homes have unsafe pool areas.

�And she fell in love with the Liotta pad the second she set foot in it. But she wanted to play house to make sure.�

Liotta designed and built the five-bedroom, eight-bathroom spread himself but put it on the market after upsetting his neighbours by crashing into their parked cars.

We bet they�re thrilled that Britney�s moving in.
