Justin Bieber has confirmed that he will take a paternity test, in light of the charges by Mariah Yeater, 20, that he is the father of her 4-month-old baby boy.

"All this stuff is dealt with by my legal team. But if they want me to then I will," said Bieber, The Sun wrote.

When questioned about what he would say to Yeater the pop sensation responded: "Nothing, I wouldn't waste my time… I guess (she's done this) for attention, but it's not something I am interested in."

"These people are not worth my thought or time," Bieber added.

According to Bieber, these "lies will eventually be exposed."

The father of Bieber's best friend has said he knew "something like this would happen sooner or later."

Justin Bieber's best friend, Ryan Butler, and his family believe that Mariah Yeater is after the pop star's money and fame, Astrochicks.com reports.

"We all knew that something like this would be coming sooner or later – that some young girl would see dollar signs and try to shake him down," said Ryan's dad.

"As his second family we gave Justin the boundaries he might not otherwise have had," He stated. "We taught him to respect women and he has been coached by his handlers on the importance of being careful and resolute."

Ryan added, "It's just stupid that people even think this could have happened. Justin would never screw up his life by having sex with some strange girl in a bathroom."

Amid the backlash from the news of Justin Bieber's alleged baby, Mariah Yeater has spoken out in an interview with "The Insider" – saying that the "court, will prove" her allegations true.

"I have provided evidence to my attorneys, and it'll show in court, to prove that my allegations are true," Yeater told Kevin Frazier, when questioned about people not believing her claims, The Telegraph wrote.

However, when asked about why the security guard, who allegedly took the 20-year-old to meet Bieber, denied taking her backstage and stated he was with the teen sensation the entire time – Yeater had no comment.

According to Yeater's attorneys, Justin Bieber had the opportunity to privately settle but his legal team ignored the claims, wrote RadarOnline.

Jeffrey Leaving, lawyer for the new mother, revealed on Dr. Drew Pinksy's "Lifechangers" show Tuesday that his team was confident that the pop star's DNA would reveal he is indeed the father of Yeater's son.

Regardless of Leaving's confidence in the paternity test, Bieber’s camp had issued a statement calling Yeater's story "malicious, defamatory, and demonstrably false."

Since news broke of Biebers alleged illicit tryst and 4-month-old baby, "Beliebers," the pop star's devoted fans, have taken to Twitter rebuking Yeater – with some even threatening to harm or kill her for her allegations.

@Bieber1DTour tweeted, "LIFE WOULD BE BETTER IF Mariah Yeater WOULD DIE."

"Dear Mariah Yeater, please don't assume things if you don't have the facts. Remember #14millionbeliebers are ready for the war," wrote @BeliebeZelle.

Justin Bieber has also used Twitter to dispute the baby claims.

"So Im going to ignore the rumors...and focus on what is real. an opportunity to help by doing what i love. Judge me on the music! Love yall!" tweeted Bieber.

Sources told TMZ that Bieber has stressed never having relations with Yeater and believes he has never met her.

A child support hearing for Yeater's son is set to take place Dec. 15.
