Mariah Yeater, 20, recently claimed Justin Bieber fathered her baby, and now, the teen star has fired back, slamming the allegation.
In a statement to "Extra," a rep for Bieber said, ""While we haven't yet seen THE LAWSUIT, it's sad that someone would fabricate, malicious, defamatory AND demonstrably false claims. We WILL VIGOROUSLY PURSUE all available legal remedies to DEFEND AND protect Justin against THESE ALLEGATIONS."
The pop star tweeted Wednesday, "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!"
Yeater, who gave birth three months ago to a baby boy, filed a paternity lawsuit against the singer and asked for financial support. Mariah maintains she had sex with Justin backstage at an L.A. show.
