Last year, a woman named Mariah Yeater sued Justin Bieber, claiming he was the father of her baby boy, conceived when the two had sex backstage at one of Biber's concerts. Bieber refused to take a paternity test--and didn't really comment on the accusation much at all--and eventually, Yeater dropped her case and walked away a creepy, disgraced liar. So why are we talking about her again?

Oh, that's right! Because yesterday, for reasons unknown, Bieber addressed Yeater directly for the first time in a tweet which read, "Dear mariah yeeter...we have never met...so from the heart I just wanted to say..." followed by a link to this video of Sacha Baron Cohen (as Borat) saying, "You will never get this."

Did something about which we don't know happen in the interim? Is Bieber just being a jerk? The mystery--much like Yeater's 15 minutes of fame--lives on.
