"If you're gonna start performing barefoot on stage regularly, @JustinBieber, may I suggest a pedicure," the father-of-two wrote on his personal Instagram account along with an up-close shot of the pop star's dirty toes. "Or maybe just, you know, trim those nails a bit yourself?"

The troubled celeb was recently spotted feeding squirrels at a public park in Boston sans shoes, which could explain the current state of his feet.
