Kingsrowe made it to Letterman!

So the Biebz was on Letterman the other night and in between failing Dave's pop quiz like, "How many continents are there on the planet" and answering questions about the paternity test, he showed the pic of the wax figure in Madrid where he was wearing the Kingsrowe hoody.

No joke. Bieber didn't know Australia and Europe were continents.
