Brody Jenner is slamming his “The Hills” co-star Stephanie Pratt.

In an upcoming episode of the hit reality show’s reboot “The Hills: New Beginnings”, Jenner, 35, sat down with co-star Brandon Thomas Lee to discuss Pratt’s insensitive comments about last year’s wildfires.

“As you know I was in Malibu for the past week doing the fire s**t,” Jenner said in a clip. “So I was, you know, it was a lot to take in. I was decompressing and we went to one of my good friend’s houses. We were having fun, and Stephanie just showed up. Stephanie’ probably the last person I wanted to see.”

He continued, “Frankie [Delgado], Audrina [Patridge] and I went to dinner the other day, and Audrina told me that, I guess Stephanie basically was just like, ‘Can we stop talking about the fires? Can we just, like, party in Vegas and have fun and not worry about it?’”

The short clip then showed a flashback of Patridge telling Jenner about the “awful” trip to Las Vegas, “Stephanie acted like a psycho. She was so insensitive, she didn’t care about you or the fires … we were all concerned about you and Kaitlynn, and she just wanted to party and drink.”

“Dude, I was fighting the fire by myself,” Jenner explained in the flashback. “I thought I was gonna die. I swear to God, I thought I was gonna die.”

“You know, here I am fighting for my house,” Jenner told Lee. “Fighting for my friends’ houses and I hear that Stephanie’s off in Las Vegas just caring about partying and drinking and hanging out. Just being very rude and disrespectful. So when I saw Stephanie I just completely snapped.”
