Brittany Cartwright Smitten Over New Guy, Things with Jax Still Bitter

Brittany Cartwright is glowing with her new man Brandon Hanson, making it crystal clear — it’s a whole mood compared to her estranged ex, Jax Taylor!

We spotted Brittany outside Casitas in L.A., and she set the record straight … Brandon ain’t official yet, and she’s not calling herself his GF. Not yet.

Still, Brittany says it’s all about fun for now, Brandon’s making her happy — and you have to watch the full video, ’cause she also spills on when they might make it official.

And while Brittany still smiles talking co-parenting with Jax, it’s clear it’s not all smooth sailing — she admits there are plenty of ups and downs.
