Scott Peterson's former mistress Amber Frey feels "relieved" after a California judge denied the convicted murderer's request for a new trial.

On Tuesday, Superior Court Judge Anne-Christine Massullo rejected Peterson's motion for a new trial in the 2002 death of his pregnant wife, Laci Peterson.

The following day, Frey addressed the ruling in a comment to Fox News Digital. "It's relieving to hear Scott Peterson will not get a new trial," Frey said in a statement provided by her attorney.

"I would have been willing to testify again. However, I am relieved that my testimony will not be necessary. If I were called to testify, I would give truthful testimony again, for the truth doesn't change over time."

Frey previously worked with police as an informant in Laci Peterson's murder case and later testified against Scott Peterson in court.

Peterson was convicted in 2005 of first-degree murder for Laci's death and second-degree murder in the death of their unborn son, Conner.

Peterson's legal team attempted to get their client a new trial after claiming a juror, Richelle Nice, lied when asked if she was ever a victim of crime during jury selection.

Nice failed to reveal that she retained a restraining order against her then-boyfriend's ex-girlfriend. Nice claimed the woman was threatening and stalking her.

Nice also failed to mention that she was involved in an altercation with an ex-boyfriend that resulted in her arrest. However, the court determined the juror's history did not warrant a new trial.

"The Court finds that several of the answers provided by Juror No. 7 on her juror questionnaire were false in certain respects," Massullo wrote in the ruling.

"The Court concludes that Juror No. 7's responses were not motivated by pre-existing or improper bias against Petitioner, but instead were the result of a combination of good faith misunderstanding of the questions and sloppiness in answering."

Peterson will serve life in prison without the possibility of parole.
