Justin Bieber has agreed to take paternity test after denying the allegation by a 20-year-old woman that he is the father of her 3 months-old baby boy.

Bieber's representative Matthew Hiltzik said on Monday the singer agreed to take a paternity test after he returns to the U.S. within the next two weeks. Currently in Europe, Bieber attended the MTV Europe Music Awards over the weekend. In the awards show, which was hosted by his girlfriend Selena Gomez, Bieber took home two awards.

The pop star's team has planned to vigorously pursue all available legal remedies to protect the 17-year-old singer.

The paternity suit was filed by Mariah Yeater last week in San Diego Superior Court. She claimed that she became pregnant with her three-month-old son Tristyn and Bieber is the father of the baby. The woman had just turned 19 when she and Bieber, then 16, had a brief sexual encounter after one of the singer's concerts in a backstage bathroom at Los Angeles' Staples Center in October 2010.

Shocked by the allegation, Bieber told NBC host Matt Lauer that he never met the woman. A bodyguard told The Insider, I had my eyes on him the entire night, this incident did not happen!

According to a source, Bieber's camp is prepared to take harsh legal action against Yeater for her claims.

On the other hand, Mariah Yeater has hired Jeffery Leving, a paternity law expert to help her win the lawsuit. As a statement from law offices Lance Rogers sent to RadarOnline.com read, Jeffery Leving is a national expert on family law issues. Mr. Leving has been named one of 'America's Best Lawyers' by Forbes Radio and selected by his peers as one of Illinois' top attorneys.

Yeater said she has proof that Bieber is her baby's daddy. During an interview she said, I've provided evidence to my attorneys and I'll show in court.
