U.S. rapper 50 Cent has joined what one entertainment website called the "Gaddafi performance regret club," making a donation to charity after news emerged that he performed for the clan of Libyan leader Muammar Gaddafi.

"In light of the ongoing events in Libya, 50 Cent will be making a donation to UNICEF, which is providing vital relief supplies to meet the needs of women and children at risk during this crisis," a spokesman for the artist told E! News.

50 Cent, whose real name is Curtis Jackson, joins a growing list of pop stars who performed for members of Gaddafi's family at exclusive parties around the world, sometimes commanding seven-figure sums in the process.

The appearances have become a major source of embarrassment since the Libyan leader's brutal response to a popular uprising against him in Libya.

Beyonce, Nelly Furtado, Mariah Carey and Usher have all issued statements saying they would donate or had already given money to charities after they appeared for the Gaddafi clan in recent years.

50 Cent did not name the amount of money he earned from a private concert given during the 2005 Venice film festival.

Media reports said that some artists were paid by Gaddafi's family merely to attend the parties.

On the Twitter social networking website, Furtado said recently that she was paid $1 million for a 45 minute set before the Gaddafi clan in Italy in 2007.
