Madonna, Madonna, Madonna. The Material Girl became the target of some serious backlash -- again -- on Thursday night (Oct. 18) at her concert in Colorado when she brandished a gun onstage.

Fans were outraged when Madge busted out a fake firearm in Denver at the Pepsi Center, feeling it was especially insensitive given the Aurora shootings three months ago. In case any of you somehow forgot the horrific tragedy: A lone attacker, James Holmes, launched a massive shooting in a midnight movie screening of 'The Dark Knight,' killing 12 and injuring 58 people.

Madonna's come under criticism for her politically charged, often violent imagery on her MDNA, but as a staunch advocate against censorship, she hasn't let that stop her. She whipped out a gun on all of her other stops on the tour and refused to change her set up for her Colorado date. WENN reports that members of the audience were so upset over her use of the prop that many of them actually called their local news outlets to complain about the stunt.

For her part, Madge insists the weapons aren't to be taken literally. “It’s true there is a lot of violence in the beginning of the show and sometimes the use of fake guns," Madonna admitted, "but they are used as metaphors. I do not condone violence or the use of guns.”

The guns aren't the only stunt Madonna's pulled on tour to raise eyebrows. She previously showed off a makeshift tattoo of President Obama's name (and called him a Muslim) and flashed the crowd. The Queen of Pop is as famous for pushing envelopes as she is for her songs, so it's not surprising that she's into shocking people to get tongues wagging -- so much so that she actually posted a lengthy manifesto defending her actions.
