The music has stopped for Warrant's Jani Lane.

On Thursday, the heavy metal singer was found dead in his room at a Comfort Inn in Woodland Hills, Calif., the Associated Press confirms. Police officers told the AP that the cause and circumstances of the rocker's death are not yet known.

Lane (real name: John Kennedy Oswald) is survived by four children, Taylar, Brittany, Madison and Ryan, from two previous marriages. (Taylar's mother is model Bobbie Brown, his first wife, who starred in Warrant's classic "Cherry Pie" video.) According to his Twitter account, his third wife is named Kimberly.

Lane joined hair metal band Warrant in 1984 and wrote the group biggest hits, including "Heaven," "Down Boys" and "Cherry Pie."

He quit and returned to the band numerous times -- finally leaving for good in 2008. In 2005, the then-overweight singer appeared on season 2 of Celebrity Fit Club. Last summer, he toured with the band Great White, filling in for lead singer Jack Russell.

The blond crooner had a history of struggles with alcohol; just last year, he was ordered to serve 120 days in jail following his second DUI arrest.
