'The Hills' Will Go 'Out With A Bang,' Audrina Promises

'I wanted to come on and get people talking,' her co-star Kristin tells MTV News before series finale airs Tuesday night.

So much drama has unfolded over six seasons of [url id="http://www.mtv.com/shows/the_hills/season_6/series.jhtml"]"The Hills."[/url] In the last season alone, viewers saw Heidi Montag reveal her drastic plastic surgery makeover, Spencer Pratt begin to unravel and watched in surprise as Kristin Cavallari put herself out there, only to be rejected by ex-boyfriend Brody Jenner. But "Hills" castmate Audrina Patridge says fans should only expect more drama when the series' farewell episode airs Tuesday night (July 13).

"It's our last season, so we're going out with a bang," Audrina told MTV News.

And while friendship has been the focus of the reality-TV series, which premiered in May 2006, Kristin and Audrina admit that it's the over-the-top mischief they've loved most about the show. And if anyone knows about trouble, it's Cavallari, who first turned up halfway through season five, but has since made the sixth and final season all her own.

"I was really nervous coming onto 'The Hills,' " Kristin confessed. "I was the new girl. Going to Heidi and Spencer's wedding, no one knew I was coming. But it ended up being pretty easy."

Cavallari also acknowledged that her now-infamous fight with Audrina at a "welcome back" party for Speidi may have sealed her fate as a "Hills" legend.

"That was the whole point. I wanted to come on and get people talking," Kristin said. "I knew that it was gonna stir things up. ... I had no idea certain things, like that fight, would have such an impact."

As for one of her more memorable lines from that nasty fight — "I'm sorry I walked up here and you guys came at me like piranhas" — the "Hills" star says it was TV gold.

"That was pretty good. It came out of nowhere," she laughed. "I was proud of that one."

Audrina, on the other hand, couldn't nail down one specific moment she'd remember most. There were simply too many to choose from over six seasons, she told us back in April.

"There's so many favorite moments," Patridge said. "It's funny because watching the show with the music, it makes it so emotional. So there's been a lot of moments, fun moments, like going on vacation and just having fun with each other. There's been so many dramatic moments and fights and tears and ups-and-downs of friendships and relationships, so really watching those — I mean, at the finale, we are probably all going to start crying. It is going to be a sad, sad moment."
