19-year old Mariah Yeater filed papers in court yesterday alleging that she had sex with 17-year-old Justin Bieber after his October 25th concert in Los Angeles, and now she wants him to take a paternity test to “scientifically confirm” he is the father of her three-month-old son. So Justin doesn’t have pubes, but he has a son. Yeah, right. Adding to the drama is the fact that he’s been dating Disney starlet Selena Gomez this whole time. The Daily Mail says:

In an affidavit, [Yeater] allegedly said a security guard working for Bieber approached her and ‘asked if I wanted to meet Justin Bieber’ backstage.

‘Immediately, it was obvious that we were mutually attracted to one another, and we began to kiss. Shortly thereafter, Justin Bieber suggested that I go with him to a private place where we could be alone.

‘He told me he wanted to make love to me and this was going to be his first time.’

She said he led her to a bathroom where ‘immediately his personality changed drastically’.

She allegedly claimed: ‘I asked him to put a condom on for protection, but he insisted that he did not want to.’

In court papers filed on Monday, she is also demanding Bieber ‘provide adequate support for my baby’.

Californian Yeater also claims that her sexual encounter with Bieber was ‘brief, lasting only approximately 30 seconds’.

Justin Bieber is a one-pump chump? That sounds about right. Everyone’s awful at sex when they’re seventeen. All the awkward fumbling and poking and prodding. It’s almost like being examined by a vet.
