Justin Bieber’s Baby Mama Mariah Yeater Goes Public Saying “She Has Evidence” [PHOTOS and VIDEO]

The mother of Justin Bieber's alleged love child goes out in public on her first exclusive interview in "The Insider" saying that she has evidence to prove that the young superstar is the father of her son.

The 20-year-old Mariah Yeater said yes to an interview where she narrated what happened on her claim as a sexual tryst at the backstage of one of Justin's performances last October 2010. Yeater said that a security guard invited her in the VIP area at the backstage of Los Angeles Staples Center.

"We went, and on the walk to wherever his destination was, he asked, or he was telling me, that he'd like to make love to me, all sweet and cute and touchy, and then when we got to, it turned out to be a bathroom, his whole demeanor changed, It went from cute and gushy, you know, to just more aggressive," Yeater added.

Unlike her revealing photos that hit the web, she was dressed demurely for the interview with Kevin Frazier.

Mariah Yeater's stability and personality are still in question after her alleged assault to her ex-boyfriend John Terranova in Las Vegas whom she also claimed the father of the child. She is currently facing charges for slapping Terranova in the face three times and for breaking the window of Terranova's current girlfriend. Terranova denied the allegations, according to Yeater's father, Frances Lippe.

In a sworn statement, she said that Bieber was the only person that could be her baby's father. She said that evidences will be shown in court to prove her allegations are true. Yeater did not specify what these evidences are.

Yeater decided to goes into public after Justin denied the allegations on NBC's Today Show wherein the popstar said that, "I'd just like to say basically that none of those allegations are true. I know I'm going to be a target, but I'm never going to be a victim."

"It's crazy, every night after the show I've gone right from the stage right to my car, so it's crazy some people want to make up such false allegations. But to set the record straight, none of it is true. Never met the woman," the singer added.
