The Justin Bieber “Baby” extravaganza launched 20-year-old Mariah Yeater into the spotlight -- and public scrutiny. Sources are now claiming the Canadian baby-mama has pointed the finger at other men before.

Like her ex-boyfriend John Terranova, for instance. The New York Post quotes him saying -- she’s a gold digger.

“Terranova scoffed at Yeater's claim that it was the then-16-year-old Bieber who impregnated her in October 2010 during a 30-second sex session in the bathroom of the LA Staples Center after he performed there. ‘I know it's not Justin Bieber … She just wants money. It's a scam.’”

Terranova says she originally told him the baby was his. And according to the Daily Mirror, she’s also said the father was a mysterious lover named “Steve.”

“A friend said: ‘Steve was her secret boyfriend for a long time. She said they made love twice.’ … Mariah’s friend said ­jobless Miss Yeater has a history of claiming to be pregnant and telling ‘stupid little lies.’”

But if this is a lie, it’s one that might get her arrested. Fox News anchors ask -- If she claimed to have sex with the Biebs when she was 19, isn’t she admitting to statutory rape?

REPORTER:“Alright, so here’s the question. If she sues him for child support and she is saying I had sex with this kid. Isn’t she admitting to statutory rape under the laws of California since she was 19 and he was 16?”

REPORTER:“She certainly is. Now, here’s what’s boding well in her favor. Generally, they’re not prosecuted. Why? Because of the proximity of the ages.   

Yeater released several photos of the alleged lovechild, Trysten.

The Daily Mail quotes her saying “Just look at his mouth. Look familiar?”

But the paper also reports, Yeater has a history of pulling...stunts.

“Court papers show that Yeater was arrested on 21st December on suspicion of battery domestic violence, injury, destroying property of another and making threatening telephone calls.”

The scandal has sparked rumors of a Bieber-Gomez split. But don’t believe all the gossip you hear -- the couple were just seen holding hands at the entrance to the MTV Europe Awards.
