Rappers aren't the only ones who attack fans. 21-year-old lead singer Alice Glass is notorious for her violent behavior during concerts. Last summer, she punched a security guard at a gig in Barcelona. There have also been reports of her putting out cigarettes on fans and pouring her always-handy vodka mixes on them. She famously decked a dude with her microphone at a show in February 2009. It's okay. We like our women feisty.
