Jeremy Piven thinks Mick Jagger dances like a "chicken on meth".

The 'Entourage' actor gatecrashed the Rolling Stones frontman's 60th birthday party in Prague in 2003 and was shocked to see the rocker showing off his "awesome" moves on the dancefloor.

The 44-year-old star recalled: "Mick Jagger and I were both born on July 26 - just different decades! I actually wandered into his 60th birthday party in Prague and witnessed him dance for five hours, sometimes to his own music.

"He was dancing exactly the way you'd think he would, like a chicken on meth. It was awesome."

It not the first time a Rock Star's moves have caught Jeremy's eye. His first crush was a 1980s punk rock star named Wendy O'Williams who used a chainsaw in her stage act.

He explained: "She was in a band called the Plasmatics. She had a blonde mohawk and appeared onstage in a 1968 Camaro muscle car with a chainsaw.

"She jumped off the car and sawed it in half while singing. I couldn't get enough of that. It's been downhill ever since. That's why I'm still single."
