50 Cent has canceled two major international music events, citing "unforeseen and unanticipated" circumstances. The rapper - who vowed to retire if rival Kanye West beat him in the album charts last week - has pulled out of performing at the MOBOs and the Vodafone Live Music Awards in London.

A spokesman for Jackson says, "50 Cent is very sad to confirm that due to a last minute, unforeseen and unanticipated change in his schedule, he will have to postpone his European Promotion Trip from September 18- 25."
