Gene Simmons "thrusted" at a female fan after performing on 'American Idol'.
The Kiss bassist took to the stage during the final of the US TV talent show on Wednesday (20.05.09) and reportedly struggled to contain himself when a pretty woman approached him backstage.
FOX News reports "After his wild performance with Kiss, Gene Simmons was clearly feeling the buzz and wanting to do more than just kiss as he came backstage.
"'Don't I look hot,' Simmons said as he stuck out his trademark tongue (which is also body-painted) before grabbing a random good-looking young girl and thrusting her as she hugged him."
During the show, Gene performed with finalist Adam Lambert, who finished in second place behind Kris Allen.
In 2005, Gene appeared as a guest judge on the show - alongside Simon Cowell, Randy Jackson and Paula Abdul - but has previously admitted he did not enjoy the experience.
He said: "You have gone out for dinner with three friends every week and you're comfortable. Now a fourth person has joined you. It becomes that horrible, icy politeness when you are getting to know somebody. I hated it."
