Teen pop singer Justin Bieber has been in the news lately for reasons unrelated to him singing "Baby, Baby" ... unless he uttered that while nailing Mariah Yeater.
The 20-year-old alleged baby mama claims she had (brief) sex with Bieber backstage after a concert last fall and that her three-month-old son is Bieber's.
She is suing Justin for child support, while Bieber, who denies ever meeting Mariah Yeater, says he will take a paternity test to prove it, then sue her right back.
Despite the inconsistencies in her story - Mariah Yeater first accused her ex of fathering the child - she's speaking out about their "affair" on The Insider tonight.
According to Mariah, Bieber was aggressive in the sack/men's room:
"He immediately took a liking to me. We just got to talking," she recalls. "Eventually he asked me, 'Would you mind if we could go somewhere and be alone.'"
"Then when we got to what turned out to be a bathroom, his whole demeanor changed. It went from cute and gushy to more aggressive," Yeater continues.
Specifically, he supposedly asked to "f--k the s--t" out of her. Obvi.
"I have provided evidence to my attorneys and it'll show in court that my allegations are true," she says, responding to claims that she's a liar and gold digger.
Asked why Bieber's security guard says he never left Bieber that night and Justin went straight to the car following the concert, Mariah says, "No comment."
Her interview airs tonight. Do you believe Bieb smushed that?
