The Sexy Back hitmaker was due to perform gigs in Sacramento and San Jose, California earlier this month, but canceled both at the eleventh hour - sending the rumor mill into a spin. Reports he had strained his voice after performing at the MTV Video Music Awards were replaced by claims he had partied too hard.

Now the 26-year-old has come clean. He told his San Jose, California audience on Sunday: "Certain bloggers said I canceled because I was hungover and they were right... I was."

I don't think he was hungover. I think he was suffering from ass-itis. How could you not with that brick house Jessica Biel is carrying around on her back side?
