Justin Bieber Becomes a Daddy?

Justin Bieber, baby daddy? His legal team is calling allegations in a reported paternity suit “malicious, defamatory and demonstrably false” and vowing to fight them.

Mariah Yeater, 20, made the claim in a paternity suit filed Monday in L.A., according to Star magazine, which said it has seen the lawsuit and its handwritten declaration from the 20-year-old single mom. A rep for 17-year-old Bieber’s legal team Tuesday told outlets including TMZ and RadarOnline that although hadn’t yet seen the suit.

The woman in question reportedly filed a paternity suit against Justin, claiming she and Justin Bieber had a special hug backstage at a recent concert at the Staples Center in L.A. … and 9 months later, she popped out a baby, baby, baby, oh.

Team Bieber told the tabloid there’s no way he could have been alone with anyone backstage at a concert.

Bieber laid out his personal plan Wednesday on Twitter: “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!
