London, April 16 : Amy Winehouse and Snoop Dogg were unable to finish a pair of collaborated tracks during a recording, thanks to their frequent dope-smoking breaks, say sources.

The two were said to have teamed up in Los Angeles last year but were allegedly far from producing a "finished product" by the end of the session.

"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," the Sun quoted a source as saying.

"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," the source added. (ANI)
