Amy Winehouse for new Gorillaz album? Sketchy Mirror article thinks so

Oh, the Mirror. They're pretty off target with their music gossip. They reported earlier this year that Blur were playing Coachella, leading many (including myself) to start planning California desert trips.
Now they're claiming that Amy Winehouse has been working on stuff for Gorillaz, much to the chagrin of her record company.
Not that this couldn't be true, and if it is...it would be interesting to say the least. However, I'd take this with a giant grain, nay, a rock of salt.
