Toronto: Rapper Kanye West has fuelled speculation that he and Drake may be about to release a collaborative record. The "Gold digger" hitmaker hinted that the project may have taken place when he took to the stage in a surprise guest appearance at OVO Fest here on Monday night, reports femalefirst.co.uk. With Drake headlining the final day of the festival, he brought out not only singers Rihanna, Future and French Montana for cameos, but West as well. Whilst West was on stage, he asked the crowd: "Are you all ready for this album? I wasn't talking about (Kanye's album 'The Life Of Pablo'). I wasn't talking about 'Views'. I want to ask you all right now: Are you all ready for this album?" Making sure the crowd understood, Drake seemed to make the announcement official, adding: "What my brother was asking before was, are you ready if we make an album? That's what he was asking."
