Lady Gaga wants you to know shes a rock star. The eccentric singer stage dived into the audience during Semi Precious Weapons set at Lollapalooza 2010 in Chicago on Friday (Aug. 6). After being reeled in by security, a nearly-nude Gaga jumped right back in, seeming to enjoy the groping from concertgoers.

If anyone ever calls Lady Gaga a fu**ing pop star, I will kill you, said Semi Precious Weapons frontman Justin Tranter. Semi Precious Weapons and Lady Gaga proved at Lollapalooza 2010 that rock n roll is fu**ing back.
