Lil Wayne has recorded 90 unreleased songs with Dr. Dre and the 'Lollipop' hitmaker insists he doesn't even know when they will be released.
The 'Lollipop' hitmaker admits the pair have recorded close to 100 tracks over the years but even he is not sure when the 'Let Me Ride' rapper is going to release some of their material.
He told MTV News: ''I've always worked with Dre. I'm not sure if you guys know how Dre works, Dre always sends you a song, so I done, probably did like 90 songs for Dre. You just never know which one he gonna put out.''
Wayne is preparing for the release of his forthcoming 10th solo album, 'I Am Not a Human Being II' in December, and while the rapper didn't say whether or not a Dre collaboration will appear on the record, he admits Kanye West has played a big part in the album.
He added: ''Yeah he got some music on there. It's crazy, actually I don't want to give too much up but he's got a big hand in the album, you'll see.
''I'll always be up to work with Dre, it's always cool with him.''
