Snoop Dogg has said Charlie Sheen is not “crazy”, despite his recent public meltdown.

Speaking to journalists at a press conference in London, the rapper said recorded the song 'Winning' with Sheen because he is a long-time friend of the former Two And A Half Men actor.

"Sheen was my friend before all this happened so I do not judge him. He called on me and I came through for him,” Snoop Dogg said.

He is conducting his business, living and functioning. "But if the station (US television network CBS) wanted to put him in a box, then what would have been crazy is staying in that situation."

Snoop Dogg was speaking at the UK launch of his new album 'Doggumentary'. He played London's Forum venue last night.
