A few years ago, a barely post-pubescent Canadian kid released a song called "Baby," which led to a phenomenon of tweenage girls going crazy and adults wishing for earplugs every time they turned on a radio.

Fast-forward to today and it looks like Justin Bieber is having "baby" issues of a completely different sort.

Last week, 20-year-old Mariah Yeater (don't worry, she's not famous, you're not supposed to recognize her name) came forward to announce that Bieber is the father of her three-month-old son and that she is suing him for child support.

Yeater was featured on The Insider on Nov. 7 in an exclusive interview, reporting, "He immediately took a liking to me. … He eventually asked me if we could go somewhere and be alone." She didn't provide any juicy details about the apparent sexual encounter (other than to say it apparently lasted about 30 seconds, ouch), but did say "I have provided evidence to my attorneys, and it'll show in court to prove that my allegations are true."

Bieber's side, obviously, denies just about everything. Bieber's security guard on the night in question made a statement saying that he never left Bieber's side that night, and that Bieber went straight to his car following the concert (Yeater's response: "no comment"). According to a statement from Bieber's camp, he'll be taking a paternity test when he gets back from his European tour in a week—and then sue Yeater right back.

On the bright side for Bieber, his girlfriend of several months, Selena Gomez, seems to be sticking by his side. A source close to Gomez told Digital Spy, "Selena just wants the world to know she is 100 percent behind Justin. They both have very busy careers but she is planning to be with him as much as she can. The whole saga has brought them closer together." Yes, Selena, that's adorable, but you know the fangirls just want to know if the 30-second thing is true or not.

While baby-daddy drama is no rare occurrence in Hollywood, this is the first time in recent memory that paternity charges have been directed toward a star with such a young fan base. Surprisingly, all of the usual loud parent groups have been silent on the issue, but we have to wonder if that will remain true if Bieber is proved to be the father of Yeater's baby. Will his role model status be overturned overnight, or is "Baby, Baby, Baby" going to get an interesting and just-as-catchy remix?
