Rapper Tone Loc's concert in Iowa was cut short on Saturday (16Mar13) after he allegedly suffered a seizure on stage.

The Wild Thing hitmaker was performing on the Court Avenue bridge in Des Moines when he collapsed in front of a packed crowd during the city's Bridge Bash.

Members of the star's entourage rushed to his aid, and promoters quickly cancelled the gig, according to Tmz.com.

No further information about his condition was available as Wenn went to press, but this isn't the first time the 47 year old, real name Anthony Smith, has suffered with health problems in recent years.

The hip-hop star collapsed on stage last June (12) from exhaustion and he also reportedly suffered a seizure in August (12) while watching a comedy show but his manager played down the incident, blaming the episode on a bout of food poisoning.
