Jax Taylor And Brittany Cartwright Keep Distance on 'Valley' Set Post-Divorce News

Jax Taylor and Brittany Cartwright were back on the set Friday of Bravo’s “The Valley” just days after she filed for divorce … and you could cut the tension with a knife!

As TMZ previously reported … Jax was served the docs from his estranged wife, BC, while filming the new season of the reality show Tuesday — awkward!

And, we just so happened to get a great view of production back underway Friday … and from the looks of what we saw, the couple was keeping their distance … both in very different moods.

Brittany seemed like she did not have a care in the world, laughing with pals … while Jax looked like he was in a funk.

Things seemed to get even more uncomfortable on Friday when BC was getting a tad too close to Jax … before a friend pulled her away.

And, there was another interesting moment on Friday … a witness at the filming tells TMZ during a scene Jax was filming with Kristen Doute … he was overheard telling her he was going out of control, and that’s the reason he had to go to rehab. The Bravo personality checked into an in-patient treatment center for 30 days in late July.

Sources connected to the couple previously told TMZ … Brittany took the initiative and decided it was time to file … since her estranged hubby has done too many things for a reconciliation to occur.
