Amy Winehouse and Snoop Dogg were held up during a recording session last year (08) - after the pair reportedly became too high to perform.
The rapper is a huge fan of the Rehab singer, and invited her to a Los Angeles studio to collaborate on a couple of tracks.
But the pair's progress was halted after they allegedly smoked too much marijuana to finish their songs.
A source tells Britain's 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.
"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."
Recent legal woes have kept Winehouse from obtaining a visa and returning to the U.S.
