Justin Bieber will take a paternity test to prove that he is not the father of Mariah Yeater's baby, People confirms.

Bieber, 17, has been adamant over the past week that 20-year-old Yeater's claims (she says Bieber impregnated her after a Los Angeles concert last year) are completely false.

The teen star says he has never met Yeater, but she is demanding a DNA test in court documents. She is seeking financial support.

A rep for Bieber told the mag:

    "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."

The "Baby" singer performed at the MTV Europe Music Awards in Belfast, Northern Ireland, on Sunday (which his girlfriend, Selena Gomez, hosted.) He won two awards, including Best Male Act, and will reportedly take the test upon his return to the U.S.

Our X17online poll revealed that 67 percent of readers think that Yeater is lying, while 32 percent of you believe Bieber IS the father of her baby.
