Though it was hard to make out through the screams of the Bieber Army, Justin Bieber went on the offensive via Today and flat out denied allegations that he impregnated Mariah Yeater. If you’ve missed the whole story, Yeater has filed papers claiming that Justin knocked her up backstage during a performance at the Staples Center in Los Angeles. See the clip and read a transcript of Justin’s statement.

If you were wondering “who did Justin Bieber allegedly get pregnant?” then here’s your answer! These are MySpace photos of Mariah Yeater, the 20-year-old California woman who claims she had a brief sexual fling with the Biebs in a backstage bathroom after his concert at the Staples Center in Los Angeles in October of last year. Mariah now has a three-month old son and she has filed a lawsuit claiming Justin Bieber is the father!

Meanwhile, Justin’s reps deny he’s a Bieber Daddy.

This is one of those things that can’t be believed until Maury confirms it, but is also crazy enough to be true. A 20-year-old lady named Mariah Yeater was invited backstage to meet Justin Bieber last October, and from her accounts, he then promptly impregnated her.
