Is Lady Gaga's gun bra offensive? [VIDEO]

• Tweet

Lady Gaga -- no stranger to questionable wardrobe choices -- wore assault rifles on her bra during a concert in Vancouver Friday, according to the New York Post, just one day after Vice President Joe Biden's met with various groups on the gun control issue.

Gaga wore similar lingerie on the cover of Rolling Stone in 2010, but that was before the Sandy Hook Elementary School massacre reignited the debate over gun violence. Gun rights advocates have also accused Hollywood and the media for it's frequent and reckless portrayal of gun use.

PolicyMic's Tom McKay called the outfit "tasteless and inappropriate."

"It rubs salt in the wounds of pro- and anti-gun advocates, and much trashier, the wounds of a despondent and horrified community that just lost 20 of its children," McKay said.

“I think it is gun porn,” Ladd Everitt, of the Coalition to Stop Gun Violence, said.

“It’s almost like she’s telling her fans, ‘The only way I can stimulate you is to show you guns and violence.’
