Wacky Stunts Stars Do on Stage When singers take the stage during concerts, they are literally the centers of attention. It's their best shot to do something crazy and make themselves heard. And that's what many stars do. Carrie Underwood used her Louisville, Ky., show on Sept. 22 to make one 12-year-old's dream come true. Chase Kurnick stood in the crowd with a sign asking the country singer, "Will you be my first kiss?" Underwood spotted the boy and asked him to come on stage. But she warned that her husband, Mike Fisher, "is somewhere in the building, maybe backstage, so he might be looking for you later." Once Kurnick made it to the stage, Underwood, 29, admitted to the pre-teen that she didn't have her first kiss until she was 14. How we going to do this? Underwood asked. "Lip to lip," Kurnick responded, getting a big laugh from the singer and the audience. She then told the 12-year-old to close his eyes, she leaned in and gave him a quick peck on his lips.

Gaga asked if it was real, took a few hits and tossed it back into the crowd. And for those of you who are wondering if I'm high right now, I am not. That is not nearly enough to get me high," Gaga giggled. Shortly after news broke of the pot smoking stunt, Staten Island Borough President James Molinaro lashed out at the "Born This Way" singer. "We have to understand that there's a tremendous influence with our youth, which I didn't have as a youth," he reportedly said. And there's the influence right there. Stop glorifying the drug use. There's Gaga. Here's this ... this ... I would call her a slut. This slut is influencing many, many children.
