Brittany Cartwright and Jax Taylor put on a united front for their son Cruz amid ‘difficult’ divorce

Brittany Cartwright and Jax Taylor put on a united front Friday as they met outside their former family home with their 3-year-old son, Cruz, amid their "difficult" divorce .

The exes appeared to be doing a custody exchange at the Los Angeles residence, as Cartwright, 35, waved at her son while Taylor, 45, carried him away from her.

She appeared to be in high spirits and smiled as she waved at her son, who was facing her as he clung to his father's chest.

The "Valley" star, who filed for divorce from Taylor on Aug. 27, dressed comfortably in gray sweats and a white T-shirt that read, "It's Lit."

Her fellow "Vanderpump Rules" alum wore jeans and a gray tee with a black baseball cap turned backward. In addition to carrying Cruz, he toted along his sippy cup and beige bookbag.

Cruz, meanwhile, rocked shorts, a forest green tee and black Nike sneakers.

Page Six reached out to the stars' rep for comment.

Taylor reunited with Cruz in late August after spending about a month in a rehab facility to work on his mental health.

Before entering the in-patient facility, he confirmed he was seeking help "to get better for" Cruz.

During treatment, he was diagnosed with bipolar disorder and post-traumatic stress disorder.

"It's been a lot to process and an emotional time for me, however I've come home to my son with a new found sense of peace," Taylor wrote on Instagram when he exited the treatment center.

"I'd be lying if I said I wasn't scared for the future but my focus is just trying to be a better version of myself than I was yesterday."

He later admitted he did not want to leave rehab because he knew the world was not going to be easy on him.

Once back from rehab, Taylor spoke out on his divorce from Cartwright and said he knew it was the best decision for their family.

He even said he hopes he and Cartwright can one day be "really, really good friends."

Meanwhile, Cartwright has been adamant that she needed to split from Taylor for her and Cruz's best interest.

In March, days after Cartwright announced she and Taylor would be separating to work on themselves, she told TMZ , "Whenever you fight with somebody for so long, there's only so much you can take, and you know, I deserve better, Cruz deserves better."

Plus, in April, she detailed the "breaking point" of their relationship and noted, "[Cruz] is our main priority no matter what."
