As has just been reported by Complex, veteran California rapper Tone Loc collapsed on stage during a performance at the Bridge Bash concert in Des Moines, Iowa last night. He fell to the floor directly after finishing a song and was quickly attended to by paramedics. The show was then shut down and everyone in attendance was asked to leave. 

For those of you who aren't familiar with Loc, he's best known for his million-selling hit singles 'Wild Thing' and 'Funky Cold Medina'.

According to USA Today, "the seriousness of the incident was not immediately apparent," but no further information has been released. Loc also collapsed on stage in Florida in 2009, and again in Atlanta in 2011. 

Here's hoping his recovery is speedy. Watch a a video of him in his prime below:
