Pop sensation Justin Bieber has denied claims by a Californian woman that he fathered a child with her after a brief sexual encounter.
Mariah Yeater, 20, has filed legal papers stating she had sex with 17-year-old Bieber Oct 25 last year following the singer's performance at Los Angeles' Staples Center.
She said he was the dad of her four-month-old son Tristyn Anthony Markhouse Yeater, who was born July 6.
Bieber's representative called the allegations "malicious and false".
The statement issued on website RadarOnline.com said: "While we haven't yet seen the lawsuit, it's sad someone would fabricate malicious, defamatory and demonstrably false claims. We will vigorously pursue all available legal remedies to defend and protect Justin."
A court hearing has been scheduled for Dec 15.
