In the recent episode of 'The Hills: New Beginnings,' Mischa Barton confronted celebrity blogger, Perez Hilton for "bullying" her throughout her career.

The showdown took place during Stephanie Pratt's return to L.A. party.

"The thing with that is, this bullying that you did for so long to so many young girls, I find it hard to let go. I really do," she said to him. "It's not just about the body shaming or outing people who are gay before they're out of the closet, all of that stuff, I just can't really accept the apology entirely on behalf of how I truly feel. I think really where I think the divide between us is I don't sit well with people who purposefully harm other people."

Perez attempted to apologize to her:

"If I could go back in time -- and I say this on my kid's life, I swear -- if I could go back in time and do things differently I would," he said but she did not believe him.

"Would you, would you really?" she asked, "You would go back in time and change all of those peoples careers you messed with, all of the people you outed?"

The convo did not end well.
