Justin Bieber denies he is the father of Mariah Yeater’s baby.

He also said that what happened in backstage between him and Yeater never happened.

During a brief interview in NBC’s The Today Show he said, “To set the record straight none of this is true.”

As fans cheered, he added that is was ‘crazy’ that anyone could make such story.

He told Matt Lauer, “I know I’m going to be the target, but I’m never going to be the victim. It’s crazy, because every night after the show,I’ve gone right from my stage, right to my car.

So it’s crazy that some people want to make up such false allegations.”

Mariah Yeater, who claimed that he fathered a child, filed in San Diego Superior Court this week. She claimed that she had a brief encounter  with Justin Bieber in Los Angeles Staples Center.

She said the sexual encounter lasted only for 30 seconds, and Bieber was embarrassed about it. She also said that Bieber was a virgin then, that’s why he did not have protection during the sexual encounter. She said that Justin wants to ‘feel everything’.

Yeater gave birth to a baby boy last July and claiming that Justin Bieber is the father of her baby because she did not have sex with anyone rather than him that time.

Matt Lauer the asked Bieber if he knew the girl, and Bieber said, “Never met the woman.”

Mariah Yeater is asking for child support and a paternity test. A hearing is scheduled on December 15.

UPDATE: According to TMZ, Yeater is facing a misdemeanor battery charge that can get her six months in jail and $1,000 fine.

She pleaded not guilty.

A police report has been released that the reason for the misdemeanor battery charge is that she slapped her ex-boyfriend on December 21, 2010. The then boyfriend and Yeater was reported arguing about a broken window on the car of his new girlfriend.
