The most recent feud is between Sharon Osbourne and Lady Gaga, after Sharon came to the defense of her daughter, Kelly. Kelly claimed that Gaga's fans had bullied her, prompting Gaga to respond to Kelly on her website. And then Sharon posted an "open letter" to Gaga, who decided to respond on her own Facebook page.
The feud heated up yesterday (Jan. 14), when Sharon, again, shared a few choice opinions about Gaga on her talk show, "The Talk."
Referring to the mean words that Gaga's fans allegedly used to attack her daughter, Sharon said, "Don't let your fans be so hideously damaging, hurtful, violent on your website. If you are a Mother Monster, monitor it. Why haven't you, as a responsible young woman, said, 'No violence on my website, no violence, no threats, no violence'?"
Sharon also vocalized her distaste for the singer wearing a gun bra at her recent concert.
"Everything is guns, guns, guns," she said. "This is not right, and she should be stopped. All I'm asking her to do is to stay true to her [anti-bullying] foundation, which she said [she created because] she wants the world to be a braver, kinder world. [She should say] 'Please don't be violent on my site.'"
So far, Gaga hasn't commented on Sharon's new jabs, but while we sit and wait, let's take a look at other celeb feuds.
