Teenage pop star Justin Bieber will take a DNA test later this month to prove he did not father a fan’s baby, and then sue his accuser, TMZ reported Sunday.

Mariah Yeater, 20, claimed in a lawsuit that Bieber impregnated her in October 2010 during a 30-second sex session backstage after the singer, then 16, performed in Los Angeles.

Bieber, now 17, denied the allegations, which he called “crazy” in an interview on NBC’s “Today” show Friday morning. He hired crisis management bigwig Matthew Hiltzik of Hiltzik Strategies to help manage the scandal.

Sources told TMZ that the “Baby” singer, currently in Europe, will take a DNA paternity test to prove he is not the father when he returns to the US in two weeks.

When the tests disprove Yeater’s claim, the sources said, Bieber and his team will sue her.

His lawyer, Howard Weitzman, has reportedly already selected a lab to conduct the DNA test.

Yeater originally told an ex-boyfriend that he — and not Bieber — was the father of her baby, the New York Post reported last week.

Bieber has denied ever meeting Yeater.
