This past November, 17-year-old Justin Bieber took a paternity test to prove that he was not the father of 20-year-old Mariah Yeater's baby. Yeater had claimed that the pop star got her pregnant at the Staples Center. Bieber promises that his upcoming album, Believe, will touch on the subject of Yeater's allegations.

I'm going to be talking about everything I'm going through, Bieber told at his album playback in Notting Hill, London on April 23. I've written a song about the whole situation with that girl who said she's having my baby - Mariah Yeater.

This isn't the first time that Bieber has mentioned Yeater recently. Bieber tweeted a message directed at  Yeater on April 21. Dear Mariah [Yeater]...we have never from the heart I just want to say...The tweet ends with a video of Sacha Baron Cohen's Borat saying you will never get this.

Yeater claimed that a backstage romp in Los Angeles got her pregnant, and filed a paternity suit against the singer in late October. When Yeater's claims were first made, her attorneys, Lance Rogers and Matthew Pre told Star magazine that She is not seeking exorbitant compensation. She merely requests that Justin Bieber provide a DNA sample to verify that he is the father of Mariah Yeater's baby, and if so, to help provide child support as required by California law.

Although Yeater claimed that Bieber was the father to her baby, incriminating texts obtained by TMZ showed the San Diego single mom singing a different tune.

Pleeease ERASE ALL MESSAGES from my mom where she says (the baby) is Robbies Son. I'll kick u when we get paid I'm trusting you pleeease, read one text released by TMZ.

Another text from Yeater read, Would you please stress to Robbie how important it is for him to be in his son's life?

Yeater eventually dropped the paternity case and admitted that her ex-boyfriend was the father to her baby, reported the Daily Mail.
