Oscar-winning actor Sandra Bullock and her celebrity biker husband Jesse James are divorced.

A court clerk in Austin, Texas, confirmed that the Bullock-James divorce was finalized Monday, just two months after Bullock filed to end the marriage.

Details of the settlement were sealed by the court, but Bullock's initial filing cited "discord or conflict of personalities" as grounds for the divorce.

Her publicist Cheryl Maisel confirmed the couple's split was complete. James's publicist, Monique Huey-Jones, declined to comment Tuesday.

The split was sparked by reports of James's infidelity that emerged shortly after Bullock's Oscar win for The Blind Side.

Bullock and the Monster Garage star met in 2003 and married in 2005. It seemed like an odd pairing — the movie star often called "America's Sweetheart" marrying the tattooed biker who had been wed twice before.

It was the first marriage for Bullock, who became a devoted stepmom to James's children: Sunny, 6; Jesse Jr., 12; and Chandler, 15.

The couple stayed out of the public eye as Bullock racked up film and production credits and James expanded his reality-TV presence, starring in his own series, Jesse James is a Dead Man.

In March, Bullock seemed to be on a career high — her romantic comedy, The Proposal, was a box-office smash, then she swept Hollywood's awards season for her Blind Side performance.

The couple was a fixture at the glittery awards shows this year and she called James "sexy" as she accepted her Screen Actor's Guild award. Backstage, he held her purse as she spoke to reporters.

At the Golden Globes, Bullock told James from the stage, her voice cracking with emotion: "There's no surprise that my work got better when I met you, because I never knew what it felt like for someone to have my back."

She did not thank her husband at the Academy Awards, instead dedicating her acceptance speech to mothers and parents everywhere.

Still, the couple walked hand-in-hand down Oscar's red carpet, celebrated together at the parties afterward and were photographed outside a Long Beach burger joint the next day.

Ten days later, reports surfaced that James had been unfaithful while Bullock was away making her Oscar-winning film. He apologized to his wife and three children from previous relationships through a statement released by his publicist.

"It's because of my poor judgment that I deserve everything bad that is coming my way," he said. "This has caused my wife and kids pain and embarrassment beyond comprehension, and I am extremely saddened to have brought this on them."

Bullock cancelled appearances to promote The Blind Side overseas, moved out of the home she shared with James and dropped out of sight. James went to rehab, but did not reveal why he needed treatment.

In April, Bullock dropped a bombshell, announcing on the cover of People magazine that she was divorcing James and had adopted a baby boy whom she intended to raise as a single mother.
