Justin Bieber On Late Show With David Letterman Paternity Test Justin Bieber may be a globe-trotting superstar, but geography doesn't appear to be the 17-year-old's strong suit.<br /><br />"I have a blast. I get to travel the world," Bieber told David Letterman while appearing on the late night host's show Wednesday evening.<br /><br />Letterman challenged the Canadian star to name them.<br /><br />"Asia, North America, South America ..." the Biebs rattled off, pausing briefly. "Um, Africa, Antarctica and the North Pole."<br /><br />"Come on, you've been to both places, I'm sure," Letterman said.<br /><br />"Australia!" Bieber replied.<br /><br />But Bieber just couldn't conjure up the name of the continent across the pond, so Letterman gave him a hint: "France."<br /><br />"Europe!" Bieber replied.<br /><br />"Here, you actually learn something," Letterman told the young star.<br /><br />Despite an online initiative that sought to send Bieber to Somalia, North Korea or Antarctica, it's unclear whether the teen has actually visited the southernmost continent.
