We'll probably never get to find out - cos the breathtakingly bald look he sported on Jimmy Kimmel's show recently was merely a bald cap.
The talk show host had whipped out a pair of scissors and pretended to snip at Bieber's hair as the show went into a commercial break - only to return to a shot of the shiny chrome-dome Bieber you see above.
"I like it," said Jimmy. "You look like a young Lex Luthor!"
Bieber admitted, "I kind of like it, too."
He looks like something that hatched out of Lady Gaga's Grammy's egg!
