UsMagazine.com has obtained Sandra Bullock's divorce papers from Jesse James.
Filed Apr. 23 in Travis County Court in Austin, Tx. (where the actress, 45, is a resident), the eight-page document states: "The marriage has become insupportable because of discord or conflict of personalities that destroys the legitimate end of the marriage/relationship and prevents any reasonable expectations of reconciliation."
The papers — filed under "B.A.S." (Bullock's initials backwards) — state that the actress and James, 40, who wed in 2005, "have ceased living together as husband and wife."
According to the papers, "They'll enter into agreement for the division of their estate."
The papers also state: "There is no child under eighteen years of age or otherwise entitled to support who was born or adopted of this marriage and none is expected." (James has three kids: Chandler, 15, Jesse Jr, 12, and Sunny, 6.)
Bullock recently announced that she has adopted a son, 3 1/2-month-old Louis.
In March, four woman claimed they had fling with James. The first, tattoo artist Michelle McGee, said she slept with the biker last year while Bullock was away shooting her Oscar-winning role in The Blind Side.
Sources previously told Us Weekly they wouldn't be surprised if Bullock filed.
"Knowing the kind of person she is, I'd be shocked if she contemplated going back to him," a pal of the actress told Us.
