Rapper Tone Loc didn’t want to be hospitalized after collapsing on stage during a weekend performance in Iowa.

It wasn’t the rapper’s first time collapsing on stage; Tone Loc had a seizure and collapsed during a 2009 concert in Pensacola, Fla.

Loc, whose real name is Anthony T. Smith, collapsed after finishing a song during a Saturday night concert on a downtown Des Moines bridge.

The concert ended abruptly while the 47-year-old was treated. Three employees of the Des Moines Register who were at the show said several minutes after Loc collapsed, fans were asked to leave.

Police Sgt. Steve Woody told the newspaper that paramedics responded after Loc collapsed, but he refused to be taken to a hospital.

Loc’s representative did not respond to messages Sunday, and it wasn’t clear why he collapsed.

Authorities said he had apparently overheated.
