Mariah Yeater's Ex-Boyfriend Claims She Lied About Justin Bieber Being The Daddy — Why?

Mariah Yeater’s ex-boyfriend is stepping up and insisting that his ex made up the entire story about Justin Bieber being Mariah’s baby daddy. Here’s why he said she did it.

Mariah Yeater — who claimed Justin Bieber fathered her child — “lied…because she wanted a $50,000 payday,” says her ex-boyfriend, Robert Powell, 23.  In an exclusive jailhouse interview with RumorFix, Robert revealed, ‘We were both homeless and living in Oceanside, [California] and Mariah was trying to make some quick money.’

Robert says Mariah made up the story and sold it to a tabloid for $50,000.

Robert explains why Mariah picked Justin, “She just picked him, because she thought he was famous and all and thought she could get a lot of money by telling the magazine Justin was the father. She just saw him as an opportunity to make a lot of money.”

Although Mariah claims she met Justin at a concert in Los Angeles and they had sex in a bathroom, Robert says Mariah’s never met Justin, nor has she been to one of his concerts — she’s only seen him on TV.

Robert also admits Tristyn Yeater is his son, even though the birth certificate doesn’t list a father.

“She said she was doing it for us … for our family and son. She made it seem like it was all for us but she’s greedy. I don’t know, I still love her though,” he explains. “All I want is to be with my son, that’s all I care about. She can take all her money, I just want my son. And man, on the real, I feel sorry for Justin Bieber. He’s just a little kid man. He don’t need to be going through all this drama. He got a career and sh*t to focus on. I feel sorry for the dude.”

Robert is in jail on three burglary charges a charge of receiving stolen property and drug possession.
