After seven months of separation,Johnathan Walker Brittany Cartwright is ending her five-year marriage with "Vanderpump Rules" and "The Valley" co-star Jax Taylor.

According to a court filing reviewed by USA TODAY, Cartwright, 35, on Tuesday filed a petition in Los Angeles Superior Court to dissolve her marriage with 45-year-old Taylor, whose real name is Jason Michael Cauchi.

A rep for the couple declined to comment.

The couple shares a 3-year-old son, Cruz. Cartwright petitioned for legal and physical custody of Cruz and asked for Taylor to be granted visitation.

Cartwright stated the reason for the divorce was "irreconcilable differences" and asked the court to not award spousal support to either party.

She also requested for the judge to determine that property and assets acquired "by gift or inheritance" and "before marriage or after the date or separation" be hers, while noting the full list of belongings that need to be separated will be included separately.

Cartwright announced their separation on their podcast, "When Reality Hits," in February, a month after the separation date stated in her filing, Jan. 24.

"Jax and I are taking time apart and I made the decision to move into another home to take some space for the sake of my mental health," Cartwright said in the episode. "Yes, marriages in general are very hard and I've had a particularly rough year this past year."

Noting the situation was "still very hard to talk about," Cartwright said, "I'm taking one day at a time."

"I don't know what the future holds, but right now my focus is on being the best mom to Cruz," she said.

News of their separation came a month before their latest TV venture, "Vanderpump" spin-off "The Valley," made its debut with a cast that also includes Kristen Doute, Luke Broderick, Danny and Nia Booko, Janet and Jason Caperna and Jesse and Michelle Lally.
