Justin Bieber Taunts Mariah Yeater via Twitter

With his motivation unclear, yet his message direct, Justin Bieber took to Twitter over the weekend and taunted the young woman who accused him of fathering her baby last year.

During his self-proclaimed #RANDOMTWITTERHOUR, Bieber aimed some pent-up wrath at Mariah Yeater and wrote:

"Dear Mariah Yeeter...we have never met...so from the heart i just wanted to say..." - and here he linked to the following Borat clip - "You will never get this. You will never get this. La la la la la."

Borat Clip: "You Will Never Get This"

In late 2011, Yeater spoke to the tabloids and claimed she had sex with Bieber backstage after a concert in Los Angeles. She then sued him for paternity of her three-month old son.

But Bieber's lawyers fought back, the suit was eventually dropped and little has been said about Yeater since December, when an ex-boyfriend came out and said he was the father of her child.

Why did Justin choose this moment to revisit the past? Who knows. But the overall message is all that matters: You suck, Mariah Yeater! Leave JB alone!

Justin Bieber Wrote a Song About Mariah Yeater

While most everyone else on the planet has forgotten the name Mariah Yeater by now, Justin Bieber is once again making it clear that this blackmailing 20-year old remains very much on his mind.

A couple days after the singer taunted Yeater over Twitter, he told reporters in London that he actually wrote a single about the young woman who tried to sue him for paternity of her child last year.

"There's a song about that girl that said she was gonna have my baby, Mariah Yeater," Justin said at a press event. "There are songs about things I'm going through. I wrote songs about different situations."

Bieber added that he penned 40 tracks for the album - titled "Believe" and set to own the music charts starting on June 19 - and isn't sure if the Yeater single will be included.

"Every song has a piece of me," the Biebs told BBC News. "It's so cool to do different styles and step out of my comfort zone."
