Eddie Markhouse says it's true, Justin Bieber is the father of Markhouse's great-grandson!
INSIDE EDITION spoke exclusively to Markhouse in the kitchen of his home in Las Vegas. He's the grandfather of Mariah Yeater, the woman who claims she had a one-night stand with Justin Bieber last year and gave birth to his son.
"She met him at a concert and he sent two security guys down off of the stage to bring her backstage to meet him and she said they partied and were, I guess, having some drinks or something and, and they, they indulged in sex," Markhouse said.
Markhouse, a retired cab driver, helped raise Mariah and has a close relationship with her. He saw the baby for the first time two weeks ago when Mariah came to visit.
"I couldn't put him down. I mean he's just a happy baby, and well taken care of, a little chubby face," he said.
Markhouse says he was kept in the dark about the identity of the father until just a few days ago, when he was told the baby was Justin Bieber's.
"She's basically an honest, good person. She's got a heart, you know, a big heart," he said. "I can't see her lying about it."
