“Vanderpump Rules” star Brittany Cartwright has filed for divorce from her husband Jax Taylor, seeking to end their marriage after five years.

The reality TV personality, 35, submitted her divorce petition on Tuesday, August 27, according to court documents obtained by The Post.

The reality star asked the court for legal and physical custody of their three-year-old son, Cruz, stating that she is open to allowing Taylor to have visitation rights.

“The Valley” star cited irreconcilable differences as the reason for the divorce and listed the couple’s date of separation as January 24. She requested that neither she nor Taylor be granted spousal support.

Cartwright and Taylor announced their separation in February.

Cartwright’s decision comes on the heels of Taylor seeking treatment at an in-patient facility to help with his mental health struggles.

“Jax has always been candid about his mental health struggles, especially during the past few months on his podcast,” Taylor’s rep said at the time.

“He has made the decision to seek in-patient treatment,” the rep added. “This is a particularly sensitive time for him and his family. They ask for privacy and respect until he is ready to speak more on this matter.”

Taylor reportedly left treatment last week and returned to work on Season 2 of “The Valley,” which has documented many of his and Cartwright’s marriage woes.

Cartwright and Taylor’s rep said, “No comment” when The Post contacted them about the divorce.

This is a developing story.
