X17 Online reveals that the Blind Side actress recently closed a deal for the "8,110-square-foot, seven-bed, eight-bath Tudor-style mansion" in the Holmby Hills neighbourhood.
The property occupies 4.1 acres and offers amenities such as an in-house screening room, library, staff quarters and a pool-side pavilion, as well as "stunning 270-degree views" of the ocean.
The house has had several famous owners, including movie star Marlo Thomas and record executive and film producer David Geffen.
Bullock previously donated $1 million to help aid those affected by the recent Japanese earthquake and tsunami.
It was announced earlier this month that a New Orleans high school class she had sponsored saw 100% of its students graduate this year.
