"Idol's" Blake Lewis Gets Nailed!

Blake Lewis' hair wasn't the only thing that turned black recently -- so did his toe!

TMZ has learned the "American Idol" be-bopper had to go to the doctor last Thursday to have his toe looked at after a hangnail turned his toe black. Sounds more painful than Sanjaya's singing!

After having his pedi-cured, sources close to Blake say the 25-year-old then boarded a private jet for a visit to his hometown of Bothell, Washington.

Now we know why Blake sometimes seems a little light in his loafers.
