LAPD: Statutory Rape Investigation Into Alleged Justin Bieber-Mariah Yeater Tryst Possible

Death threats from angry “Beliebers” could soon be the least of Mariah Yeater’s troubles: The tattooed and pierced San Diego woman claiming to have a three-month-old son with pop sensation Justin Bieber could find herself at the center of a statutory rape investigation after the alleged sexual tryst that she claims left her pregnant.

Yeater had just turned 19 in Oct. 2010; that’s when she says she and Bieber, then 16, had a brief sexual encounter after one of the singer’s concerts at the Staples Center in Los Angeles. The single mom gave birth to a baby boy named Tristyn in July and believes Bieber is the father. She’s petitioned the court for a paternity test “to scientifically confirm that he is in fact the father of my baby.” She also wants him to provide “adequate support” for the child.

Mariah’s age is what makes things a bit dicey: See California law states that anyone over 18 who has sex with a minor not more than three years older is guilty of a misdemeanor, which carries up to a one-year jail sentence.

Bieber’s camp has denied he is the child’s father. In fact, Justin says he doesn’t even know Mariah.

On Thursday, Los Angeles Police Commander Andrew Smith told The Associated Press that no report has been taken about the incident, but noted that his department could file one against Yeater for statutory rape.

“If it’s brought to our attention, of course we’ll look into it.”

Lawyers for Yeater don’t exactly deny that the blonde likely broke the law if/when she bedded The Biebs, but that doesn’t get Justin — himself the product of teenage parents — off the hook for supporting the kid.

“The issue of statutory rape even if she’s guilty, hypothetically, that has no bearing on the duties to provide child support,” says Matthew Pare, who represents Mariah. “It’s a totally separate issue.”

Meanwhile, Bieber’s die-hard fan have been heavily hating on Mariah via Twitter…death wishes and all.

“Roses are red, violets are blue Mariah yeater we are gunna kill you,” wrote one fan, while another so lovingly Tweeted: “No one deserves hate…. But I guess Mariah Yeater is the only exception.”

The only antidote in all this hating is that Mariah’s grandfather has kindly spoken out about his granddaughter. Eddie Markhouse told Inside Edition this week:

“Mariah doesn’t lie. I don’t know the whole story. But, from what I understood, she met him at a concert and he sent two security guards down off of the stage to bring her backstage to meet him. She said they partied, had some drinks and they indulged in sex…She’s basically an honest good person. She’s got a big heart. She’s a good kid and she loves this baby.”
