Some people don't know when to quit.
The 20-year-old California woman who first claimed in November that Justin Bieber fathered her 5-month-old son, is sticking to that story despite mountains of evidence that suggests otherwise.
In an interview with the Chicago Sun-Times, Mariah Yeater was asked if her ex-boyfriend Robbie Powell is her son Tristyn's real father?
To which Yeater replied, "Yes, I know him," and then insisted, "He is not the father, and he's locked up and out of the picture."
Powell had come forward on Dec. 13 claiming he was the father of Yeater's child. He told RumorFix that Yeater lied and claimed she made $50,000 from selling her story to a tabloid.
"She just picked [Justin Bieber], because she thought he was famous and all and thought she could get a lot of money by telling the magazine Justin was the father. She just saw him as an opportunity to make a lot of money," he said.
Powell, who is currently in jail after being arrested on Nov. 26 for burglary and drug possession, says he's sure he's the father of Yeater's baby -- and even expressed sympathy for the popstar who is now tangled up in his personal drama.
Despite this, Yeater told the Chicago Sun-Times she is still pursuing her paternity claim against Bieber out of court.
"I dropped the lawsuit, but never my claim. I still definitely want a DNA test and I want to refile my paternity case -- I do believe he is the father," she said.
The lawsuit has somehow turned into a bigger case of 'he said, she said," as Bieber announced he took a DNA test on Nov 18. and his lawyers said they couldn't get in contact with Yeater or her lawyers afterward to compare.
In an this endless game of back and forth, Yeater's lawyer, Jeffery Leving, claims Bieber's team has been "sluggish and non-cooperative" concerning the test -- claiming Bieber's counsel hadn't told him where the DNA is secured.
Leving also told the paper, Yeater still has the ability and legal right to refile the paternity suit at any time, adding that if negotiations with Bieber's team does not result in DNA testing of everyone under mutually agreeable terms and controlled conditions, then Yeater will likely refile in court.
