Hahaha, how did I not know about this earlier? The hot new phrase on the music scene is "Tongue-Diving" ... where an artist starts making out with a random fan in the crowd during their show. Check out the video of Adam Lambert tongue-diving during his pretty awesome covers of Mad World and 20th Century Boy. Oh - and he does it twice!! (4:00 and 5:00 marks) And PS: I love how he's all sparkly and glittery like Edward Cullen in sunlight!

Billie Joe from Green Day is apparently all about the tongue-diving too... but he's a major rockstar so he makes his fans come on stage for a kiss instead of going into the crowd. Here he is a few weeks ago tongue-diving a male fan in England:
