You may well ask now that Lady Gaga and Kelly Osbourne, plus her mother Sharon Osbourne and even Kelly's fellow fashion police officer, Joan Rivers, are engaged in a slap fest via interviews, "open letters" on web sites, and defiant tweets.
This latest celebrity feud started when Kelly O. mentioned in a recent interview with Fabulous, a UK magazine, that some in Gaga's huge fan base, the "Little Monsters," had cyber-bullied her, suggesting she kill herself or hoping she'd be raped.
Gaga, a leader in the campaign against cyber bullying, responded with an open letter on her website, expressing some sympathy and apologizing for her fans. But she also criticized Kelly and Rivers and their show, Fashion Police on E! network for "making jokes about artists and celebrities as if we were animals in a zoo."
This set off Kelly's mama, Sharon Osbourne, a judge on America's Got Talent, who put up an open letter of her own on her Facebook page, calling Gaga "a hypocrite" and "bully" and other choice epithets.
"You know it would have been much more dignified of you to do this privately," she lamented. "Are you so desperate that you needed to make this public?"
Kelly meanwhile defended herself on Twitter, at one point quoting Hollywood icon Bette Davis, who said, "When a man gives his opinion, he's a man. When a woman gives her opinion, she's a bitch."
And Rivers pointed out to E! Online that Gaga should remember that Fashion Police is a comedy show.
Naturally the celebrity media are delighted to cover another feud, eagerly following the back and forth and inviting readers to chime in, too. People has the whole story, so does TMZ and all the usual celeb followers, plus the Twitter feeds of all involved.
But you wonder about the point, since everybody seems to agree on the bottom line, which is that bullying, including cyber bullying is bad. They're just too busy sending potshots past one another to notice.
