Recently on 'The City' (Tue., 10:30PM ET on MTV), a styling mishap set roommates and coworkers Whitney Port and Roxy Olin at odds, and led to a big fight. Whit said she was "constantly disappointed," and Roxy said she wanted to move out.

It was no idle threat. Whitney came home to find her roommate packing her bags. "I can't really take the tension here," Roxy said. "I thought you would be like happier that I was leaving."

Whitney responded, "I just feel like we're leaving things on such a weird note ... No hard feelings, I guess." As Roxy slid out the door, she told Whitney she'd call later. Doubtful. Can these friends (since high school) patch things up?

It's girl vs. girl on 'The City' (Tue., 10:30PM ET on MTV). Apparently, our glamorous young women are running into a little trouble. Whitney wants to "style" a hot new rock band, but she feels that Roxy isn't obeying her every whim. Naturally -- this being 'The City' -- the whole thing inevitably leads to conflict.

The rock band makes a last minute wardrobe change, and Whitney blames her friend. Roxy attempts to explain that the clothes she was given weren't appropriate, but that's not going to stop a good fight! The two girls confront each other in the hallway behind the concert, and Whitney starts making empty threats. Specifically, she threatens to get Roxy in trouble with their boss.

Oh, Whitney. Don't you realize that you ladies are both stuck on an MTV reality show? Neither one of you is going away, no matter how many fights you get into. So maybe just learn to deal with each other.

Trouble ensued on 'The City' (Tue., 10:30PM ET on MTV) when Whitney Port and Roxy Olin went to Miami to put on a runway show. During the model auditions, Roxy noticed a rival designer casting one of their models. Whitney just had to intervene.

"I noticed she's trying on your stuff," said Whitney. "But I know you're [on the runway] right before us, so it's probably not possible for us to share any models. And I know I saw her first, so I kinda have dibs."

The designer simply chuckled and strutted off. Said Whitney: "What's her problem? This bitch keeps stealing our models!"

'The Hills' and 'The City' are gearing up for new seasons, and there's plenty of romances, break-ups, partying, new betrayals and new alliances ahead.

Both shows premiere April 27 on MTV, and the love lives and careers of Heidi, Spencer, Brody, Audrina, Justin, Whitney, Roxy, Olivia and Erin will continue to dominate the new seasons.
