Brittany Cartwright says her relationship with Jax Taylor is improving when it comes to their kids … but, they still have an “explosive” dynamic — and, fans will bear witness to it all on season 2 of “The Valley.”

We caught up with the reality television star in Downtown Los Angeles this week … and, we had to ask her about the second season of the show which premiered Sunday — and contained some intense moments.

If you haven’t seen the ep, spoilers … Brittany claims Jax flipped a table and hit her with it after he found out she sent a sexy video to her friend even though they were estranged at the time.

Brittany tells us her co-parenting relationship with Jax is improving … though she adds their relationship will always be “explosive” — so, it doesn’t appear it’s going perfectly smooth. Plus, she says the divorce is still moving forward.

As for what fans can expect in future season 2 episodes … listen to her answer — anyone hoping for smooth sailing for Britt is going to be sorely disappointed.
