Rapper Eminem farted in a microphone during his tour, Anger Management. The singer, 32, was performing at Madison Square Gardens in New York, when he dropped his trousers and farted into a microphone, according to New York Post.

The show also featured 50 Cent's posse (G Unit) and Eminem's crew (D12), plus cameos from Busta Rhymes, M.O.P., Mobb Deep, Pit Bull and Mase (who didn't rap but just smiled).

The Anger Management Tour will go to UK next month, with concerts at the Milton Keynes National Bowl on September 9 and 10.

According to Contactmusic.com, Eminem will be joined by D12, Obie-Trice and Stat Quo performing with him. He will be performing tracks from his four chart-topping albums, including the recently released 'Encore' album.

50 Cent's set will include performances from G-Unit members Tony Yayo, Lloyd Banks, Young Buck, Olivia and DJ Whoo Kid.

It will be the first time 50 Cent has toured the UK since the release of his T"he Massacre" album which hit the top spot when it was released in March 2005.
