The singer announced the cancellation on his website, saying, "unfortunately, while the creative process has been exciting and I'm pretty certain we're going to deliver the best album of my career so far, the timing hasn't adhered to the schedule I originally envisioned."

He added, "My team and I have made the agonizing decision to put off the tour until 2013 when we know we will have the new music done and will be ready to fully unveil the creative vision through the album and the live experience."

We're wondering how many normal people could get away with an excuse like that at work.

Here's the kicker: Kanye West might be part of the problem. The mercurial, exacting rapper has been collaborating with Legend on the new recording. West does not have the reputation of being particularly speedy in the recording studio.

"Kanye is my friend and he's never treated me like a jackass," Legend quipped earlier this year, referring to President Obama calling West a "jackass." "He's one of the most talented artists we know in this generation and I feel very fortunate to be able to work with him."

Legend said those who purchased tickets for the canceled shows will get a refund.
