Talk about baby mama drama! More of The Insider's interview with Justin Bieber's alleged baby mama, Mariah Yeater, 20, has been released -- and the footage shows Yeater breaking down several times -- and even walking out!

Yeater is shown footage of Bieber denying that he is the father of her baby, and she starts to cry.

A few minutes later, when asked about whether she fears investigation for statutory rape (she was 19 when she allegedly slept with Bieber, while he was 16), she starts to cry again.

And when asked if anyone who was also backstage at the Los Angeles concert last year where she and the Biebs allegedly hooked up could substantiate her story, she starts to ... cry again. Then, Yeater walks out of the interview.

Bieber's camp says he will take the paternity test that Yeater asked for in court in two weeks, when he returns from Europe. See more of Yeater's breakdown after the jump.
