CHICAGO — Who says Lady Gaga doesn’t like to kiss and tell?!
On Friday, the pop star made an unexpected appearance on stage with Semi Precious Weapons at Chicago’s Lollapalooza music festival, where she did some crowd surfing and planted a kiss on the band’s frontman, Justin Tranter.
"If anyone calls Lady Gaga a pop star I’ll f–ing kill them," Tranter said after the show on the band’s website. "She is a rock star and she is helping Semi Precious Weapons bring rock and roll back."
Gaga, who just racked up a record 13 nominations for the 2010 MTV Video Music Awards, sat in and played drums during the song "Magnetic Baby." Of course, the superstar also brought down the house at Grant Park with her own lavish stage production that rocked Lollapalooza’s opening day.
