Justin Beiber's Fathering Drama... it's not the end! (Update)

Justin Bieber is steeling himself after it was alleged he impregnated a fan - because he's convinced it "won't be the last" time he's rocked by lovechild accusations.

The 17-year-old star was left stunned after Mariah Yeater, 20, claimed she fell pregnant after having sex with the singer backstage at a concert in Los Angeles.

Bieber has adamantly denied the rumours, but admits he's prepared for other women to fabricate similar stories.

He tells TMZ.com, "It's the first time that something like this has happened, so it's kind of really crazy. I'm sure it won't be the last (time) but it's just sad that it has to happen like this. I mean, it's just weird that people automatically assume that it was true. But I knew eventually it would die down.

"There's a lot of people that get accused of different things, especially in my business. It's something that comes with the territory. There's a lot of lies that happen and you just gotta focus on what's important. I stay away from all that stuff. I really have been so busy promoting my Christmas album, I haven't had any time to be on the computer."

And the singer insists he's fed-up of fielding questions about Yeater.

When asked if he's annoyed with the controversy, he adds, "A little bit. People saying, 'Are you going to be a father?' and all this stuff. Someday I will be, but not any time soon."

Beiber Accused of Fathering a Fan's Baby

Justin Beiber is facing a paternity lawsuit filed by a 20-year-old woman claiming the underage pop singer is the father of her 3-month old son. Whoa — Desperate psycho? Or corrupter of minors? Neither is a good look, girl! RadarOnline reports (via Star magazine), on October 25, 2010, Mariah Yeater (19 at the time) alleges she was propositioned by 16-year-old Bieber (now 17) backstage following his L.A. concert. Yeater swears in court papers, “On July 6, 2011, I gave birth to a baby boy. That was exactly 36 weeks and two days after the sexual encounter with Justin Bieber. Based upon the timing as well as the fact there were no other possible men that I had sex with that could be the father of this baby, I believe that Justin Bieber is in fact the father of my baby.”Of course, the potential baby-mama wants a paternity test and child support for little Tristyn Anthony Markhouse Yeater (Bieber?).No surprise here, J-Biebz’ rep denies the story and reacted with this statement: “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.”Justin, who is dating 19-year-old Selena Gomez, also tweeted his response, “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!” A hearing is scheduled for the end of December… Not so great publicity on the same day he drops a new Christmas album. His “Beliebers” are going to hunt down and viciously attack this Mariah girl, aren’t they
