Calif. woman claims Bieber fathered her baby

A California woman has filed suit against pop sensation Justin Bieber, claiming he's the father of her 3-month-old child, a celebrity magazine is reporting.

Enrique Castro Mendivil, AP A 20-year-old California woman claims pop sensation Justin Bieber is the father of her baby.

Star magazine said 20-year-old Mariah Yeater is demanding that Bieber, 17, take a paternity test. She claims she and Bieber had sex backstage at a concert at the Staples Center in Los Angeles when she was 19. The age of consent in California is 18, so if true, Yeater would be admitting to a misdemeanor.

The celebrity website radaronline.com carried a statement from an unidentified representative for Bieber: "While we haven't yet seen the lawsuit, it's sad that someone would fabricate the malicious, defamatory and demonstrably false claims. We will vigorously pursue all available legal remedies to defend and protect Justin against these allegations."
