Mariah Yeater Cries, Storms Out of Interview [VIDEO]

Mariah Yeater seems to crumble under pressure.

The 20-year-old who accused Justin Bieber of fathering her three-month-old son recently sat down with Kevin Frazier of CBS' The Insider to discuss the ongoing saga.

Yeater has defended her accusations against Bieber, which cite that she and the singer met at his concert in October 2010, had a sexual liaison, and she became pregnant.

However, when Insider interviewer Frazier started grilling the young mother about the charges, she crumbled.

Could any of those other girls that were in that room substantiate your story? Frazier asked.

Yeater becomes teary-eyed and holds her head in her hands. She then begins looking around the room and shaking her head.

Frazier asks the question again. Yeater gets up and storms out, saying, Give me one minute.

Yeater did a series of interviews with The Insider about her supposed relations with Justin Bieber. This particular portion of the interview is the most emotional.

During other questioning, the California native said, I still am.. I'm scared, Yeater said. I was very hesitant. This is a very serious matter [and] it had to be brought to his attention. To everyone's.

But, she added, Everyone has a past, everyone makes mistakes. There's nothing wrong with that.

Yeater claims that a security guard approached her at the October 2010 concert and brought her backstage, where she and other girls met with Bieber. Supposedly, the pop star only had eyes for her.

Justin Bieber recently agreed to take a paternity test. If and when DNA test proves he is not the father, Bieber and his team will slap Yeater with a lawsuit, sources directly connected to Bieber told TMZ.

This love child saga has been going on for weeks, as Bieber denies all allegations against him before the scheduled December court date.

Foruntately for the singer, the controversy has had no effect on his success.

Bieber's album Under the Mistletoe debuted at No. 1 on the Billboard Top 200 chart after its Nov. 1 release, according to Reuters.
