When celebrities attack: George Lopez vs. Kirstie Alley, plus four other good Twitter feuds

Lopez: On Kirstie Alley’s twit list (Reuters - Mario Anzuoni ) Remember when celebrities had to wait until hitting the morning talk show circuit before engaging in a public feud?

I’m thinking about the 2006 battle between Donald Trump and Rosie O’Donnell, in which the two traded ridiculous barbs that included words and phrases like ”sit and spin, my friend,” “a real loser,” and “my nice fat little Rosie.”

So I think we can all agree those were the good old days.

Today, self-proclaimed fat actress and current ”Dancing With the Stars” contestant Kirstie Alley is calling (tweeting?) for the kidney of comedian George Lopez, who lampooned Alley’s first “DWTS” performance Thursday evening on “Lopez Tonight.” In fact, he compared her to a pig. Hell hath no fury like a reality show contestant scorned.

• Rihanna vs. Ciara. Let’s be real. When you take two R&B princesses, give them smart phones and add a healthy dose of cattiness, the situation is bound to boil over. The quote that started it all? Ciara’s comment in February about Rihanna to Joan Rivers. "I ran into her recently at a party. She wasn't the nicest.”

• Ashton Kutcher vs. CNN. Alright, this one wasn’t really a feud, but Kutcher and the news network did engage in a friendly competition to see who could collect 1 million Twitter followers first back in 2009. (Kutcher won.) These days, all it takes is an epic drunken bender to yield such results.

• Nick Cannon vs. Chelsea Handler. Protecting the honor of his wife, Mariah Carey, Cannon unleashed a stream of nasty tweets directed at the comedienne last October. Among the insults used? ”angry ugly whitetrash.”(And that’s only 21 characters, if anyone’s counting.)

• LeAnn Rimes vs. the woman who was married to Eddie Cibrian. My, how far the golden children of the 1990’s have fallen. Now that I think about it, “The Trollop Who Stole My Husband and Embarrassed Me on the Internet” sounds like a hit country record. (Rimes and Brandi Glanville have since made up.)
