London:
Rapper Kanye West was partying at New York's Dream Downtown with Leonardo DiCaprio, Erin Heatherton and The Hangover director Todd Phillips and stunned fellow revellers when he pulled out a laptop and got DJ Reach to play the tracks he had on it.
One onlooker told the New York Post newspaper: "He was dressed in black pants and a leather T-shirt. He danced and lip-synced [to his songs].
"The room looked stunned. People were standing around with jaws literally dropped."
It was recently claimed that Kanye - who is in a relationship with Kim Kardashian - wants to make an album composed of animal noises.
The 35-year-old rapper experimented with them on his Watch The Throne album with Jay-Z and wants to take the sounds further by developing them into an entire record.
A source said: "Kanye's telling friends this is his next ingenious plan.
"He's become so obsessed with roars, barks and jungle noises that he's experimenting with putting them on a recording."
