Bieber will take the test when he returns to the U.S. in two weeks, confirms a source close to Bieber who is not authorized to speak publicly. The teen star may also sue his accuser, Mariah Yeater, and anyone else involved in filing the suit.

Bieber’s spokesperson said in a statement, “We'll vigorously pursue all available legal remedies to protect Justin and to hold those involved with bringing this suit accountable for their actions.”

TMZ was the first to report the news.

Yeater is sticking by her allegation that she and the teen star conceived a child in a bathroom at the Staples Center last year. In an interview with Insider, the 20-year-old said she has evidence to prove Bieber is the father, but declined to reveal what that is.

If the child is Bieber’s, police said Yeater could be investigated for statutory rape.

“We are encouraged that Justin Bieber will voluntarily take the paternity test.  That is the only way to definitively determine who the father is,” Yeater’s lawyers told TMZ. “The paternity suit was filed in good faith and it will continue despite the threats.”

Bieber seemed unperturbed by the allegation on Friday’s “Today” show, where he denied that he and Yeater have ever met. He continued playing it cool while accepting an award at the MTV EMAs.: “There’s been a lot of [stuff] on the Internet lately, but I pulled through it.”
