Amy Winehouse & Snoop Dogg Collaboration 'Delayed'

Amy Winehouse and Snoop Dogg apparently hooked-up in the studio last year, but allegedly became so high on marijuana that their collaboration was never completed.

The rapper is said to have invited the singer out to Los Angeles to work on several songs, claims The Sun.

"Amy came to the studio buzzing with ideas and the pair got on really well, even though Snoop turned up in his dressing gown with slippers on, which had Amy giggling." A source tells the UK newspaper.

"They were working at a frenetic pace at first but as the day wore on and more smoke breaks took place, the work rate slackened. By the time their studio time ended they had a pair of tracks sketched out but no finished product."
