Justin Timberlake sent temperatures soaring with girlfriend Jessica Biel after reportedly giving her a lap dance.

The singer was first seen tearing away from a crowd of screaming girls at the after-party for his William Rast show at Hudson Terrace.

"There was just a crush of girls, everyone went wild," the New York Post quoted a source as saying.

The star then apparently made a beeline through the crowd to a red velvet curtain where Biel was waiting for him.

The source continued: "He opened the curtain and stepped Jessica behind it, then wrapped them in it before giving her a long kiss."

The source added: "He ended up giving her a lap dance. It was pretty raunchy."
