The 'That '70s Show' star was sentenced to 30 years to life in prison in his Los Angeles rape case.
Earlier this month, Phillips and her mother-in-law, Carol Masterson, looked visibly upset in Los Angeles Superior Court after the actor was sentenced to 30 years to life in prison in his rape case.
Phillips kept her sunglasses on the entire time and remained stoic. Afterward, Phillips and Masterson's mom were rushed off to a waiting vehicle. Masterson's brother, Christopher, also attended the sentencing hearing.
Phillips' reaction Thursday was in stark contrast to her reaction after Masterson was found guilty on two counts of forcible rape back in May, where she let out a wail as the verdict was read by Judge Charlaine F. Olmedo in L.A. Superior Court. The reaction prompted the judge to reprimand the actress, telling her to keep her composure or leave the courtroom.
After Olmedo handed the sentence on Sept. 7, the victims exited the courthouse hugging and in tears. Actress Leah Remini, who had been roped into the case when Masterson alleged she was the architect behind the accusations, was also there with the victims as they left the courtroom together. Remini wore an all-pink suit.
After sentencing Masterson, the judge had pointed words for the disgraced actor.
"Mr. Masterson, you are not the victim here," the judge said. "Your actions 20 years ago took away another person's choice and voice. Your actions 20 years ago today were criminal, and that's why you are here."
During the reading of victim impact statements, Masterson remained stoic. He was brought into court flanked by guards and his attorney, Shawn Holley. Phillips arrived looking solemn.
Phillips, who donned a button down and slacks, kept to herself and seemed numb to what was happening around her. She walked into court with a stoic face.
Masterson, 47, and Phillips, 43, tied the knot in October 2011 during an intimate ceremony in a small town in Ireland. The couple welcomed daughter Fianna in 2014.
Then, on Sept. 18, Phillips filed for divorce in Santa Barbara County Court. In court documents obtained by ET, Phillips cited "irreconcilable differences" as the reason for the dissolution of the marriage, and requested spousal support, attorney's fees and that her legal name be restored to Phillips.
Phillips also requested legal and physical custody of her and Masterson's 9-year-old daughter, though she is willing to allow Masterson visitation.
"Ms. Phillips has decided to file for divorce from her husband during this unfortunate time. Her priority remains with her daughter," Phillips' lawyer, Peter A. Lauzon, told ET in a statement. "This period has been unimaginably hard on the marriage and the family. Mr. Masterson was always present for Ms. Phillips during her most difficult times of her life. Ms. Phillips acknowledges that Mr. Masterson is a wonderful father to their daughter."
