Throughout this entire ordeal, Justin Bieber has maintained that he was not the father of Mariah Yeater's baby, even going as far as to volunteer to take a paternity test.
And as you can see in this clip from tonight's The Late Show with David Letterman, the singer has officially submitted to a cheek swab.
"It's pretty crazy. People make up false accusations. It's gonna happen, being in the spotlight," Bieber says. When the host offers up that he "smelled a weasel" from day one with this story, Bieber adds, "I can smell a weasel too."
