Jax Taylor spoke of his drama with girlfriend Brittany Cartwright during last night's episode of Watch What Happens Live.

Following the latest episode of Vanderpump Rules season five, Taylor, who has been feuding with Cartwright over her alleged hookup with Kristen Doute since episode one, addressed their issues.

“Listen, whether it did or did not happen, it’s in the past," he explained, according to a report by Reality Tea. "I was more mad because I couldn’t get into the house! I was so mad, trying to call Brittany, I was coming home from SUR, I had a couple drinks and I was just angry because she wasn’t answering her phone. So when I got in, I could care less if she was sleeping with girls or not, I was just so mad because I couldn’t get in the house, so I kind of took it out on her. What I saw really didn’t help but..”

As for his reaction to Cartwright's alleged behavior, Taylor explained, “It was a mistake and I’m sorry and I apologize. I shouldn’t have ran off, I was just mad and angry and I didn’t know what to do. I was kind of just in shock. It happened six months ago and it was stupid.”
