First he rocked Beliebers with his mature, shorter do, and now Justin Bieber is about to send fans into another frenzy. The 17-year-old says he is giving his razor a rest and wants to grow some whiskers.

"im not shaving for a month so you all can see my mustache," baby-faced Bieber tweeted on March 5. "im pumped."

But are fans going to be excited for a nearly bearded Bieber? Possibly.

Reaction to his freshly trimmed mop-top in February was mostly positive, and a lock of his snipped strands sold on eBay for $40,668, with proceeds going to charity.

Will Bieber auction off his stubble when he grows tired of the scruff?
