As she began her song “Heavy Metal Lover” on Friday, the 26-year-old singer rode a motorcycle onto the stage and at some point while getting on or off, she ripped open the back of her Versace latex pants, exposing her bare butt!

But fear not Little Monsters! This is the same singer who has worn a dress made out of meat and often goes pants-less, so embarrassment really isn’t her thing… Gaga continued on with the song as if nothing had happened! (Or maybe she just didn’t feel the breeze back there)

The next day, Gaga got back to seriousness and responded to the criticism she faced from Sharon Osbourne and her daughter Kelly after the “The Talk” co-host called the singer, “nothing more than a publicly seeking hypocrite and an attention seeker” after Gaga had written an open letter to Kelly for her not-so-nice critiques of Gaga’s weight on E!’s “Fashion Police.” In 2009, she called Gaga a “butterface” (meaning she has a nice body, but not a pretty face) and when the singer gained 25 pounds last fall, Kelly snarked, “I think she is pregnant.”

On Saturday, Gaga tweeted and posted on her Facebook page, “The ‘real world’ can be cruel, why not try to change it into a better place? I am an activist. Nobody takes adolescents seriously, I do. My letter to @MissKellyO was open, because her statements on cyber-bulling were public & as a youth activist I'm compelled to be involved.”

And on Monday, it was Osbourne's turn again, as she addressed the feud on her show, "The Talk." "My opinion is, Gaga wants a kinder world. Don't let your fans be so hideously damaging, hurtful, violent, spread violence on your website," the talk show co-host began. "If you are a mother monster, monitor it.  She has a huge group of people that work for her that monitor her website.  Why haven't you, as a responsible young woman, said 'No violence on my website, no violence, no threats, no violence.'  However, everything is guns, guns, guns... Cut to her first performance on this new tour. She's wearing two guns coming out of her breasts. Now, on her website, if anybody had the time to pick out how many times guns, guns, guns were mentioned, this is not right and she should be stopped."

Who do you think is right in this feud … Kelly or Lady Gaga? And does Sharon need to let her daughter fight her own battles? Let us know your thoughts.
