Pop singer Justin Bieber wrote a song for the San Diego woman who claimed he fathered her child -- but it's no love song, baby.
Mariah Yeater, 20, claimed Bieber fathered her baby during an encounter at the Staples Center in Los Angeles on Oct. 5, 2010, according to a paternity lawsuit. Bieber and his reps have publically denied the claim and the case was thrown out in court.
On Saturday night, Bieber tweeted "Dear mariah yeeter [sic]...we have never met...so from the heart i just wanted to say..." with a link to the character Borat singing "You Will Never Get This."
He also told New York Post reporters in London that he plans to write a song about Yeater in his upcoming album, Believe.
KNSD-TV, NBC's affiliate in San Diego, was unable to obtain the sealed court documents alleging paternity, but Radar Online posted a copy of the documents obtained by Star Magazine online.
Justin Bieber was 17 years old at the time of the alleged encounter.
