US rapper Kanye West is to attend anger management classes following recent spells of erratic behaviour, it's been claimed.

West's management company apparently raised their concerns after the rapper launched an attack on people who criticised his appearance at the recent Bonnaroo Festival.

Earlier this year the rapper also asked a journalist “when was the last time you enjoyed yourself” after he gave West's Glow in the Dark tour a bad review.

"Kanye's management team came up with the idea,” a source told the Sun newspaper.

"His mood swings were beginning to play a part in his commercial enterprises as people felt he was miserable all the time."
