Which was the biggest celeb smackdown?
CHARLIE VS. DENISE
When Richards landed It's Complicated, an E! reality show, Sheen took his ex to court – unsuccessfully – to keep daughters Sam and Lola off-screen. He even told PEOPLE, "I think we should all just boycott the damn thing!" Later – in an understatement – Richards admitted to Ryan Seacrest, "Charlie and I don't agree on much these days."
JESSICA VS. CARRIE
After Simpson started dating Underwood's ex Tony Romo, the former Idol told Allure that the Dallas Cowboys quarterback still calls her. "The phone will ring and it'll be him, and I'll maybe not answer," Underwood said. Simpson denied that her beau was reaching out, telling Nashville radio station 107.5 The River, "Tony and I both laughed at that." She added, "I look at his call log."
PAM VS. JESSICA
In a retaliation against vegetarian Carrie Underwood (who claimed that her ex and Simpson's current beau, Tony Romo, still calls her), Simpson wore a shirt proclaiming that "Real Girls Eat Meat." PETA spokeswoman Anderson bashed Simpson in the press, calling her a "b–tch" and a "w–re." Simpson retaliated, telling Nashville's 107.5 The River, "I respect my elders."
JOHN VS. DAVE
After the presidential candidate canceled on Letterman's Late Show at the last minute to rush back to Washington, D.C., amid the financial crisis, the talk-show host spotted him giving an interview in N.Y.C. to Katie Couric. The move led to Letterman poking fun at McCain night after night. "Someone is putting something in his Metamucil," he joked. Three weeks later, McCain made up the date – and apologized.
WHOOPI VS. THE ACADEMY AWARDS
On the big night in 2008, Goldberg – the first black host of the Oscars ceremony – was left out of a montage of emcees, a snub that left her in tears. "Undoubtedly, I pissed somebody off once again," Goldberg, who's also a trophy winner, said on The View. "It was an absolute oversight," producer Gil Cates told PEOPLE. "I feel very, very badly that she was left out." She accepted his apology, saying, "I know him as a great gentleman."
JORDIN VS. RUSSELL
While hosting the 2008 MTV Video Music Awards, Brand poked fun at the purity rings the Jonas Brothers wear (symbolizing abstinence before marriage). When presenter Sparks took the stage, she told the audience, "It's not bad to wear a promise ring because not everybody – guy or girl – wants to be a slut." Brand then apologized, sort of. "Promise rings, I'm well up for it," he said. "[But] a bit of sex, it never hurt anybody."
MEG VS. DENNIS
While promoting her film The Women (in which she plays a scorned wife), Ryan alleged that her ex-husband of seven years had cheated on her. "Dennis was not faithful to me for a very long time, and that was very painful," she told InStyle magazine. Quaid hit back, saying, "I find it unbelievable that Meg continues publicly to rehash and rewrite the story of our relationship."
LINDSAY VS. MICHAEL
No strangers to public battles, the elder Lohan triggered this round when he bashed his daughter's girlfriend to E! News. "People never even knew who Samantha Ronson was until she met Lindsay," he said. "Samantha is using my daughter." Lindsay lashed out on her MySpace blog, saying her father "has become a public embarrassment and a bully – to my family, my co-workers, my friends and a girl that means the world to me."
TINA VS. ARETHA
When Turner was introduced at the Grammys as "the queen," Franklin – long-called the "queen of soul" – took offense. "I am not sure of whose toes I may have stepped on," she said. "I dismissed it as a cheap shot for controversy." Turner later joked about the incident to USA Today, saying, "She's the queen of soul, and I'm the queen of rock 'n' roll ... Her ego must be so big to think she was the only one." That, too, didn't sit well with Franklin, who fired back, "I never figured her to resort to tacky press just to sell a few tickets."
