Justin Bieber's supposed baby mama is MIA after DNA test

Forget Carmen Sandiego, where in the world is Mariah Yeater?! The gossip circuit is abuzz with whispers that Justin Bieber's "maybe baby mama" has mysteriously dropped off the radar just days after the teen heartthrob did his best impersonation of a Maury guest and submitted his DNA for a paternity test.

Yeater, a 20-year-old single mom from San Francisco, thrust herself into the national spotlight (and the crosshairs of Beliebers) earlier this fall. In an exclusive interview with Star last month, the blonde claimed to have bedded Biebs during a 30-second romp that followed his performance at the Staples Center in October 2010. As Mariah tells it, the brief (emphasis on this) encounter left her pregnant.

She gave birth to a son, Tristyn Yeater, in July and almost immediately fingered Justin as the father. Bieber, on the other hand, has consistently denied the paternity claims and now he's taken the steps to clear his name. The "Baby" crooner had his cheeks swabbed for DNA at an undisclosed testing facility in New Jersey last Friday, according to Radar Online.

"It's an extremely reputable facility, and there are surveillance cameras everywhere to ensure tests are done with complete integrity. Justin's test should be completed by the end of the week. It's time for Mariah to put up or shut up, and submit the baby to a test," an informant tells the site.

Bieber has vowed to sue Mariah and her attorneys once the DNA proves he's not a teenage dad. Ah, which brings us to the most recent curveball. Now that it's time for Mariah to produce baby Tristyn for a round of genetic testing, the tattooed and heavily-pierced bane of JB's existence is officially nowhere to be found.

The newly-assembled legal team representing the usually press-friendly young woman have also flown the coop. Yeater's disappearance has left the Bieber camp biding its time until it can clear the pop titan's good name and sue the pants off Mariah for "abuse of legal process." As if they'd have to sue her to get her pants off! If you've been keeping up with your celebrity dish, you'll recall that Mariah appeared to have prematurely ousted herself as a big fat faker last week. She was caught sending texts which asked friends to "erase all messages" where she mentions that baby Tristyn isn't Bieber's.

Interesting.

Loose-lipped informants close to the case doubt Mariah will ever provide the sought-after DNA, after all, doing so would not only invite a hefty lawsuit from Justin, but also potential legal prosecution from the Los Angeles Police Department. No reports have been filed, but a rep from the LAPD says Yeater could face statutory rape charges just based on the published reports about her alleged liaison with Bieber. Under California law, having sex with a minor when you're less than three years older than the victim is a misdemeanor, which carries up to a one-year jail sentence.
