Look out for the claws on these resident mean girls of reality TV!

Sharon Osbourne and Megan Hauserman, Rock of Love: Charm School

After trading verbal insults — Hauserman, 29, told Ozzy Osbourne's wife that she was only famous because she managed a "brain-dead rock star" — on the VH1 show, Sharon spilled a drink on the contestant and pulled her hair. Hauserman filed a lawsuit against the British star for battery, negligence and infliction of emotional distress.

Lauren Conrad and Heidi Montag, The Hills

The former friends became archenemies after Conrad accused Montag and her boyfriend Spencer Pratt of spreading a rumor that she had a sex tape with her ex, Jason Wahler. The two have rarely spoken since their famous confrontation — when L.C. shouts, "You know what you did!" — but seem to put the past behind them in the MTV show's upcoming fifth season.

New York and Pumkin, Flavor of Love

When Pumkin got booted from Flavor Flav's house because he thought she was only trying to make a career as a reality star on the VH1 show, she got into a shouting match with fellow contestant New York. "You are just as ugly on the outside as you are on the inside," Pumkin said before spitting in her rival's face. As Pumkin tried to make a run for it, New York grabbed her hair before crew members could separate them.

Paula Abdul and Kara Dio Guardi, American Idol

After seven seasons with Simon Cowell and Randy Jackson, Abdul might not have been eager to welcome new judge DioGuardi. She told tabloid OK! that having a fourth judge "doesn't work." Although she said her quote was out of context, DioGuardi was hurt, saying that "Paula has a right to her opinions, but I was disappointed."

Kelly Bensimon and Bethenny Frankel, Real Housewives of New York

When Bensimon joined the cast of the Bravo hit, she and the 38-year-old chef did not get along. After Frankel criticized Bensimon -- who was arrested in March for assaulting her ex-boyfriend -- for refusing to help with a charity event, Bensimon told Frankel she was above her because "I won't put up with your antics and bulls--t... While you're busy talking, I'm busy doing things. I don't like you."

Rikki and Vikki Mongeon, A Double Shot at Love

The twin sisters don't always agree, and when it came time to deliberate over the next elimination on MTV's bisexual dating show, things got heated. Frustrated that they couldn't agree on a contestant, Rikki pushed her sister off her chair and onto the floor before storming out of the room.

Melissa Rycroft and Molly Malaney, The Bachelor

It was bad enough that Jason Mesnick dumped his fiancee, Rycroft, on national television, but when he admitted that he was really in love with ousted contestant, Malaney, Rycroft said, "they both did betray me." The 25-year-old added that Malaney doesn't "have the characteristics I would want to be friends with."

Whitney Port and Olivia Palermo, The City

In the season finale of the Hills spinoff, these frenemies take passive-agressiveness to a new level. Port finally confronts her Diane von Furstenberg coworker about stealing credit for her Elle cover look, but the socialite refuses to admit her fashion job faux pas.

Brooke Hogan and Linda Bollea, Brooke Knows Best

Hulk Hogan's family has had its share of spats, but when Linda Bollea, 49, filed for divorce from her husband and took up with her daughter's former classmate, 19-year-old Charlie Hill, Brooke did not think mother knew best. "I'm totally freaked out," Brooke said. "I personally don't like it at all, or condone."

Gretchen Rossi and Tamra Barney, Real Housewives of Orange County

Barney accused Rossi of cheating on her late fiance Jeff -- he later died of cancer -- and that they had a "relationship of convenience" in which Rossi dated a man named Jay. During a reunion show, she denied Barney's story and said Jay was just an ex. Rossi -- who also did some heavy flirting with Barney's son -- added, "Do you really hate me that much that you need to say the most ludicrous thing I've ever heard?"

Lauren Conrad and Kristin Cavallari, Laguna Beach

Before she began pulling out her claws on The Hills, she got practice fighting with the one-year-younger Cavallari. They were never friends, as Cavallari was dating Conrad's long-time childhood friend Stephen Colletti. When they broke up, Cavallari then dated Conrad's sometimes love interest, Brody Jenner.

Kenley Collins and Heidi Klum, Project Runway

The pin-up designing finalist could not take constructive criticism. She consistently talked back to the judges -- giving Klum some eye-rolls and more than a few "whatever" remarks and told Michael Kors that she doesn't "follow collections." And if that wasn't catty enough, Collins was arrested in March for assaulting her fiance, Zac Penley, with their pet cat!

Omarosa and Ereka Vetrini, The Apprentice

The ever-catty Omarosa alleged that she was victim to an on-camera racial slur made by Vetrini. Although most thought she was referring to the time when Ereka said, "the pot [was] calling the kettle black," Omarosa accused her of saying the N-word -- which was denied by NBC, the show's producer and Donald Trump himself.

Paris Hilton and Nicole Richie, The Simple Life

After filming their third season of their popular Fox show, the BFFs had a falling out, and Hilton went so far as to publicly proclaim that socialite Kimberly Stewart would replace Richie in the next installment. The on-again, off-again duo ended up filming two more seasons. In one, the heiresses never shared screen time, but in the final season, they reunited and worked as summer camp counselors.

Audrina Patridge and Lo Bosworth, The Hills

When Bosworth and bestie Lauren Conrad decide to throw Patridge a birthday party to smooth over tensions -- the three were roommates, but Patridge lived in the guest house -- Bosworth ended up leaving because she was uncomfortable with Patridge's friends. Later, Patridge told Bosworth, "We'll never be friends." Bosworth adds that Patridge also called her "super bitchy" on the premiere of the show's fourth season.
