Brad Pitt has splashed out $1.1 million buying his fifth house on one estate.

The 'Inglourious Basterds' star - who uses the huge Loz Feliz property as his base in Los Angeles when he's in town with partner Angelina Jolie and their six children - has bought the 3,232-square-foot home next door to his main home.

The 46-year-old actor managed to knock an additional $400,000 off of the asking price of the two-bedroom house, which sits in a 0.25 acre lot and boasts a stone fireplace, a huge main room, a bonus room, plus a bar area and secret cave.

The Hollywood star bought the home from the estate of the late Anne Tyler Sherman through his Mondo Bongo Trust.

Prior to buying the property, Brad already owned four other luxurious houses in the compound.

These included a five bedroom, 5,760-square-foot main Craftsman-style house, an adjoining 1,653-square- foot house, a 1,307-square-foot strip of vacant land, and a 1,534-square-foot house.

Brad and Angelina recently donated $1 million to help the earthquake victims on the Caribbean island of Haiti, and donated over $6.8 million to charity last year.
