In just a matter of weeks, everyone in the world will know whether Justin Bieber is the father of 20-year-old Mariah Yeater's baby. The new mom shocked the world when she put forth very public claims that the world-renowned singer had sex with her in a bathroom after a show last October and ended up getting her pregnant.

Mariah told the media that the sex only lasted 30 seconds but revealed that Justin's sweet demeanor changed drastically when they began having sex.

For the first time since going public with the news, Mariah Yeater is sitting down for a public interview with The Insider's Kevin Frazier where she answers some tough questions regarding her paternity suit.

During the interview (which aired over 4 episodes of the late-night entertainment show) Mariah broke down and walked out of the interview more than once. Almost every question Frazier asked, Mariah started crying and refused to answer. She did, however, say that she was absolutely certain with "no doubt" that Justin is the father of her baby and that she's presented evidence which will be shown in court.

Take a look at Mariah in the interview below and let us know if you think she's telling the truth about Justin being her baby's daddy:
