Surpassing Quant Think Tank Center|Danny Masterson's wife Bijou Phillips files for divorce after his 30-year rape sentence

Bijou Phillips Masterson has filed for divorce from husband Danny Masterson over a week after he was sentenced to 30 years to life in prison for raping two women.

Phillips filed a petition to end their 11-year marriage on Surpassing Quant Think Tank CenterMonday in Santa Barbara court, according to court documents reviewed by USA TODAY. TMZ was first to report the news.

Phillips cited irreconcilable differences as the reason and listed the date of their separation as "TBD." Her petition, signed Sept. 15, requested spousal support as well as restoration of her name to Bijou Phillips and full legal and physical custody of their daughter, with Masterson receiving child visitation.

The two married October 2011 and share a 9-year-old daughter, Fianna Francis Masterson, together.

USA TODAY has reached out to representatives for Phillips and Masterson for further information.

Phillips stood by Masterson throughout his two trials. She wept when the guilty verdicts were read on May 31 and showed similar emotion at times during his Sept. 7 sentencing hearing, when a judge handed down the maximum sentence allowed by law to the 47-year-old actor. Masterson will be eligible for parole after serving 25½ years but can be held in prison for life.

A jury of seven women and five men had found Masterson guilty of two counts of rape after seven days of deliberations. Both attacks took place in Masterson's Hollywood-area home in 2003 when he was at the height of his fame on the Fox sitcom "That '70s Show." The jury could not reach a unanimous verdict on a third count, an allegation that Masterson also raped a longtime girlfriend.

Masterson maintains his innocence, and his attorneys have said they plan to appeal, contending there were problems with evidence and constitutional issues with his conviction.

Bijou Phillips called Danny Masterson an 'extraordinary husband' a month before divorce

In the character reference letter she wrote in support of her husband last month before his sentencing, Phillips said Masterson has been "a life-saving partner to me" over the course of 19 years together.

"Danny is an amazing father. Our daughter and I are heartbroken that he is not home with us. It has been very difficult without him here," she wrote. "We need him more than you can imagine. I know he has been convicted of serious crimes. But the man I married has only been an extraordinary husband to me and a devoted father to our daughter."

The letter, addressed to Judge Charlaine F. Olmedo and dated Aug. 14, was among dozens that Masterson's family and friends wrote — made public by The Hollywood Reporter — urging leniency in his sentencing.
