Bieber, 17, has already vigorously denied the 20-year-old fan’s claim that he got her pregnant, saying he never even met her. He will take the test once he returns to the U.S. from Europe next week, a source tells PEOPLE.
The pop superstar is also likely to sue Yeater and the people representing her to show there are consequences to making false accusations.
“It’s disappointing that people would stoop so low, but somebody needs to stand up to them,” says the source.
Yeater is seeking financial support from Bieber. A rep for Bieber told PEOPLE in a statement: “It’s sad that someone would fabricate malicious, defamatory, and demonstrably false claims. 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 first reported the DNA-test story.
