Following a one-month hiatus from touring, the pop star kicked off the North American leg of her Born This Way Ball as stormed the stage in Vancouver, Canada, on Saturday, with guns blazing — literally.

In one of her frequent, and always fabulous, mid-concert outfit changes, Gaga appeared in a guns-adorned black brassiere, paired with a pink ponytail and army-green parachute pants. Mother Monster’s firearm fashion may hit some raw nerves, as it came just a day after Vice President Joe Biden met with Congress and the National Rifle Association (NRA) to revisit gun control laws in wake of the Sandy Hook elementary school massacre in Newtown, Conn., which left 26 people dead.

Gaga wouldn’t be the first pop star to bring gun play on stage. Last October, Madonna caught criticism for wielding a prop weapon and pretended to shoot an imaginary criminal during her MDNA tour concert in Denver, Colo., just months after the movie theater mass shooting in the nearby city of Aurora.

But Gaga has hit headlines recently for more than her ever-controversial fashion choices. Mother Monster has been wrapped up in a war of words with Kelly Osbourne, as the two have battled back and forth about bullying. First the Fashion Police host slammed the pop star’s followers as “the worst” for their criticism of her weight struggles. Then Gaga responded with an open letter to Osbourne, berating the E! star for “pointing in the camera, laughing, and making jokes about artists and celebrities as if we are zoo animals.”
After Sharon Osbourne came to the defense of her daughter — blasting Gaga as “hypocritical and full of contradictions” and branded Osbourne’s work a simple product of the “real world” — the “Born This Way” singer shot back on Twitter over the weekend.
“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,” Gaga wrote. “My letter to @MissKellyO was open, because her statements on cyber-bulling were public & as a youth activist I’m compelled to be involved.”

But despite all the flying fur, Kelly Osbourne is still a self-proclaimed “big fan” of the pop star. “All I have to say on this subject is that I love Lady Gaga!” she told People on Saturday. “I made stupid mistakes when I was 25, as well, when I accused people of doing things that were wrong. We all live and we learn, and like I said, I’m a big fan of hers.”
