Justin Bieber had no problems talking about taking a DNA test on last night's Late Show with David Letterman.
Justin even went so far as calling the alleged baby momma accuser Mariah Yeater a "weasel." He told Dave:
"I mean I could smell a weasel. People make up false accusations. I am 17, but it is going to happen….Being in the spotlight. I took it. They just swab your mouth."
Justin is absolutely certain that the kid ain't his considering he's never even met
the weasel the girl.
