Grandfather defends Bieber accuser

NEW YORK, Nov. 3 (UPI) -- Mariah Yeater, the woman who says Canadian pop star Justin Bieber fathered her son, "doesn't lie," her grandfather told TV's "Inside Edition."

Yeater is suing Bieber, 17, for financial support for her 3-month-old son, Tristyn. The 20-year-old California woman has said she became pregnant when she had sex with Bieber after a Los Angeles concert last year.

"Mariah doesn't lie," Eddie Markhouse, Yeater's grandfather, told "Inside Edition."

"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."

Bieber's lawyer this week denied the allegations in a statement.

"While we haven't yet seen the lawsuit, it's sad that someone would fabricate malicious, defamatory and demonstrably false claims. We will vigorously pursue all available legal remedies to defend and protect Justin against these allegations," the statement said.
