Video has emerged of Australian singer Shannon Noll being pinned down during an arrest outside an Adelaide strip club last night.

Witnesses said Noll had been kicked out of the Crazy Horse club on Hindley Street.

"He got really aggressive and kept saying 'I'm Shannon Noll let me back in to the Crazy Horse' and then punched a security guard," a witness told 9NEWS.

The 41-year-old from NSW was charged with two counts of assault.

Noll is best known for his platinum-selling debut single, What About Me. It was the highest selling single in Australia for 2004.
