| by Michael Allen

Mariah Yeater, a 20-year-old woman who claims that Justin Bieber fathered her three-month-old baby, told 'The Insider' how she allegedly met and had sex with the teen pop star (video below).

Yeater described how Bieber's demeanor supposedly changed after he got her alone in a bathroom backstage after a concert. Yeater claimed that Bieber refused her request to wear a condom during the 30 second sex act.

Bieber has indicated that he'll take a paternity test to prove the child is not his. He is currently in Europe, but his lawyers say that he will take the test within a couple of weeks. Bieber was recently spotted at a gay bar, but insisted that he likes girls.
