HOLMDEL, N.J. (AP) _ Lenny Kravitz collapsed from heat exhaustion during a weekend concert, a spokesman for the arena said today.

Kravitz, wearing bell bottoms and a long sleeve coat, played for 40 minutes Sunday night, then walked off and collapsed backstage, said Jim Steen, director of marketing for the PNC Bank Arts Center. His band played for another 15 minutes without him before the show was stopped.

Kravitz was treated by the house doctor and left on his own, Steen said.

Kravitz, who has been touring with the Black Crowes and Everlast, was the final act in the first concert held at the arts center this season.
