Where Is Drizzy Drake?

Drake is currently the golden child of hip-hop. He has a co-sign from just about every major commercial artist in hip-hop right now including Lil' Wayne and Jay-Z. He is the only rapper to receive a GRAMMY nomination from a song on a mixtape (sure, So Far Gone was re-released as an EP but it was still the same mixtape we all had to begin with). He's proving himself to be the only successful actor to transition into rapping as a full-time career. His debut album, Thank Me Later, debuted at number one on the Billboard charts just last month and has recently been certified Gold.

At the height of his success, at the time most critical in his career to be on tour promoting his new album, Drake has just canceled his European tour. Why would he risk so much at a time like this?
