Rock star Jon Bon Jovi got an icy reception from authorities for a pre-dawn frolic at New York's Wollman Rink, but the long-haired musician thawed out police, who Saturday called him "the nicest guy in the world."

The New Jersey rocker, best known for his double-platinum album "Slippery When Wet," was cavorting on the ice at the Central Park ice skating rink about 3:30 a.m. Friday with his girlfriend, bodyguard and another woman when they were interupted by Parks Department officers who issued them a summons."He said, `I'm Jon Bon Jovi,' " said police Sgt. Tony Michalek, decribing the superstar's response to Parks Department officers who asked his name as they wrote the summons.

"They said, `Yeah, right, and I'm Santa Claus"' when the musician could provide no identification, Michalek said.

"He was extremely friendly," said Michalek, adding "I've been a police officer for 20 years and I've met plenty of celebrities - I've met them obnoxious and nice and he was definitely the best."
