Jax Taylor's mother skipped his wedding to Brittany Cartwright, the Vanderpump Rules star said on Tuesday's episode of Watch What Happens Live on Bravo.
The 40-year-old SUR server added that she didn't even call to congratulate him.
Jax and new bride Brittany, 30, appeared on the talk show following the season eight premiere of Vanderpump Rules and their June 2019 nuptials in Versailles, Kentucky.
An audible sigh emerged from Jax when a caller asked whether his mom attended his wedding at Kentucky Castle.
'I'm sorry,' he continued. 'I'm a little stubborn, but I'm the son, and I just feel like… it's just a touchy subject. The answer is, ''No, she didn't make it''.'
Jax has been estranged from his mom, Marie Cauchi, since his father passed away from cancer in December 2017, and she failed to call him home.

In an episode from last season, Jax explained that his parents' marriage had already been 'on the rocks; she was talking about leaving my dad about a year before he got cancer.'
'Toward the end, my mom would say, ''Oh, he's fine,'',' Jax recounted then. 'We didn't know he was in ICU. I would have been there in a heartbeat if I knew he was in ICU.'
Jax never said goodbye to his father, which deeply upset him, and he was already expressing doubts last December about whether his mother would attend the wedding.

He said he had a great time nonetheless, and Brittany noted that she was planning to change her last name to his original one, Cauchi, once they had some of the children they wanted.
When host Andy Cohen, 51, asked about their wedding guests' behavior, the couple said that castmate Scheana Shay, 34, was the drunkest and flirtiest, while Tom Schwartz, 37, was among the most emotional.
Southern Charm star Shep Rose, 40, was the 'worst guest ever,' they declared, half-joking, explaining that he had talked during the whole wedding and videotaped them constantly.

Jax later shared that he had personally 'trashed' his groomsmen's suite at the wedding venue afterward—something Brittany said she'd never heard about.
At the end of their busy day, the couple's wedding night was 'sleepy and sexless,' they admitted, though they'd had sex before it, and still had sex three days a week.
As wedding favors, the couple gave their guests Mamaw's Beer Cheese, a favorite treat among the Vanderpump Rules cast, which a Kentucky company is manufacturing for Brittany to sell.

The couple then talked about their current relationship, and Andy asked if Jax was still putting himself first, as he'd once told Brittany's family he would.
'Oh pshhh,' Brittany laughed, waving the idea away. 'No! I am number one in this group!'
