Vanessa Bryant has filed for divorce from her NBA star husband citing "irreconcilable difference."

According to court documents, Vanessa is seeking to dissolve the marriage on charges of irreconcilable differences. Celebrity website TMZ quoted sources Friday as saying Vanessa is ending the marriage because she believes Kobe has been unfaithful, again.

"She's been dealing with these incidents for a long time and has been a faithful wife, but she's finally had enough," TMZ reports.

Vanessa has also filed for joint legal and physical custody of their two children, Natalia, 8, and Gianna, 5, documents show.

According to TMZ, the couple has no prenup, meaning 29-year-old Vanessa is entitled to half of everything. She's also hired noted divorce lawyer Laura Wasser, who has worked with Angelina Jolie, Britney Spears and, most recently, Maria Shriver and Kim Kardashian.

Kobe, who filed his response to the divorce minutes after Vanessa filed her petition, says he will pay her spousal support.

The couple released a joint statement Friday saying they have resolved all issues privately, with the assistance of counsel.

In 2003, Bryant was arrested for sexually assaulting 19-year old hotel employee Katelyn Faber in Colorado.

Bryant had checked into The Lodge and Spa at Cordillera in Eagle County in advance of undergoing knee surgery nearby.

Faber accused Bryant of raping her in his hotel room the night before Bryant was to have the procedure.

Bryant admitted an adulterous sexual encounter with his accuser, but denied her sexual assault allegation.

The accusation tarnished Bryant's reputation, as the public's perception of Bryant plummeted, and his endorsement contracts with McDonald's and Nutella were terminated.

In September 2004, the assault case was dropped by prosecutors after Faber refused to testify in the trial.

Afterward, Bryant agreed to apologize to Faber for the incident, including his public mea culpa: "Although I truly believe this encounter between us was consensual, I recognize now that she did not and does not view this incident the same way I did. After months of reviewing discovery, listening to her attorney, and even her testimony in person, I now understand how she feels that she did not consent to this encounter."

A civil suit was later filed and settled out of court.
