New York - Justin Bieber is denying allegations he fathered a child and says he has never met the woman who filed the paternity suit against him.
The teen heartthrob said on Friday during a brief appearance on NBC's Today show: "None of it is true."
He called it "crazy" that anyone would make up such a story.
The paternity suit was filed in San Diego Superior Court by Mariah Yeater.
She had just turned 19 when she says she and Bieber, then 16, had a brief sexual encounter after one of the singer's concerts.
Los Angeles police have said Yeater could be investigated for having had sex with a minor.
On Friday Justin posted the following update on his Twitter page: "@todayshow thanks for letting me set the record straight. what is real are my fans...this album...and this charity work. see u guys the 23rd"
Bieber, on hand to promote a Christmas album, is to return to the Today to perform live on November 23.
