Inside 'The Hills: New Beginnings' Premiere

"You're not that special ... why are you such a dick?" Audrina hurls at her ex.

Almost everyone was out to get Justin Bobby Brescia on Monday's new episode of "The Hills: New Beginnings," as the drama involving him, Audrina Patridge and Stephanie Pratt finally came to a head.

In case you haven't been following the saga so far, Audrina and her ex started hanging out again following her nasty divorce, but she was getting mixed signals about what they were really doing. At the same time, he started becoming closer to Stephanie and wouldn't deny it when asked during a group trip to Vegas whether something more was going on between them.

After admitting she was at her "wits end" with Justin while getting drinks with new friend Mischa Barton last night, Patridge explained where things stood between her and Brescia. "I was 19 when I first met Justin. We had amazing times and then we had rough patches, but we always stuck it out and we were always there for each other no matter what," she said, "Now I feel like that's gone, I've lost one of my best friends."

Driving a wedge between them is Pratt, who Audrina met up with later in the episode. As the two sat down with Patridge's friend Joey -- who slammed Stephanie in a previous episode -- Audrina told Spencer's sister she did see "behavior" that concerned her.

"I did not hook up with him," claimed Pratt, as Patridge said she didn't care either way, she just wanted to "squash this and move on from it." Pratt responded by telling the two women, "I have not done anything wrong and you're so desperate that I've done something wrong, it's frightening."

Audrina said their relationship was "a little hurtful" to her, before Pratt stormed out of the meeting.

The entire cast -- minus Brody Jenner, wife Kaitlynn Carter and Audrina -- later gathered at Frankie Delgado's house for a party, where Stephanie called out Justin in front of everyone for never outwardly denying they had hooked up.

"I've told her time and time again, she's pulling at my belt loop in Vegas, I'm like, stop, it's not happening," he then claimed of Audrina -- also in front of the group -- as Mischa became frustrated he was making these accusations while Patridge wasn't there to defend herself.

Barton then took it upon herself to confront Justin directly, as the two had a private conversation inside Frankie's home. Justin tried to make Audrina look desperate by bringing up how she had called him 10 times in the early morning hours while in Vegas, but Barton wasn't having it, saying she was calling everyone to see what they were all doing.

"Justin, she respects you as a f--king friend for the past 10 years. You're not being a good friend to her. You and Stephanie, the bond that you have going, it's not a good friend to Audrina, you've been on and off with her," she told him. "She doesn't care about Stephanie, she cares about you and you should care about her."

"I think it's disrespectful, talking behind her back, but that's kind of how Justin rolls," she then said in a confessional.

The episode ended with one final dinner meeting between Patridge and her ex ... or, at least, the start of a dinner that abruptly ended with Justin walked out.

"I feel like I don't know where I can be just friends with you before you think maybe something else could be happening," he told her. Audrina hit back, telling him, "You're not that special. Why do you think I always wanna be with you? I try to make it clear."

When he accused her of tugging at his belt again in Vegas, she shot back, "Why are you such a dick? I feel like I'm losing a friend Justin. You used to be there for me."

"I was until it got too f--king heavy, it's too heavy," he replied. "I don't even respond to you textses [Ed. note: yes, that's how he pronounced it], that's how much I don't want to be involved in it. Your textses are this long and it's about your ex boyfriend and it's about your divorce, stop!"

"I don't think we can be friends," she finally told him. "I couldn't agree more," he replied, before he walked out.
