Justin Bieber, 17, denies being the father of a California woman’s three-month-old baby. His publicist released a statement yesterday that read: “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.” Mariah Yeater, 20, claims Justin propositioned her on October 25 last year, which led to them having unprotected sex in a backstage area at L.A.’s Staple’s Center, following one of his concerts. She was 19 at the time and Justin would have been 16. Yeater has filed a hand-signed affidavit in a California Court, claiming Justin is her son Tristan’s dad, and has demanded a paternity test, followed by “reasonable child support, effective immediately.” A court hearing has been scheduled for December.
