Mariah Yeater from California has claimed Justin Bieber was a virgin when they had a seedy liaison backstage at one of his concerts.
Mariah Yeater, 20, who alleges that Justin Bieber is the father of her baby, said he had told her he was a virgin before hastily removing her clothes in a bathroom.
The young woman also claims that her sexual encounter with Justin Bieber was “brief, lasting only approximately 30 seconds”.
Mariah Yeater reportedly claimed in court papers that she had sex after the singer’s October 25, 2010, concert at the Staples Centre in Los Angeles.
In an affidavit, Mariah Yeater allegedly said a security guard working for Justin Bieber approached her and “asked if I wanted to meet Justin Bieber’ before shepherding her backstage.
“After waiting for a short period of time with several young women, Justin Bieber appeared and engaged me in conversation.
“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.
“I agreed…and on the walk to a private area, he told me he wanted to make love to me and this was going to be his first time.”
Mariah Yeater said Justin Bieber led her to a bathroom where “immediately his personality changed drastically”.
“He began touching me … at the time I asked him to put a condom on for protection, but he insisted that he did not want to.”
Mariah Yeater now wants Justin Bieber to take a paternity test to “scientifically confirm” he is the father of her three-month-old son, according to Star magazine in the U.S.
In court papers filed on Monday, Mariah Yeater is also demanding Justin Bieber “provide adequate support for my baby”.
Justin Bieber’ spokesman denied the “malicious” allegations while the singer himself dismissed them as “gossip”.
Mariah Yeater claims she was 19 when she was seduced by Justin Bieber, who is currently dating Selena Gomez, 19, best known for her role on the Disney show Wizards of Waverly Place.
Justin Bieber has publicly blasted casual sex in the past, saying: “I don’t think you should have sex with anyone unless you love them.”
But Mariah Yeater may be the one who is in trouble because Justin Bieber was 16 at the time of the alleged incident.
Under California law, the legal age of consent is 18 and police are required to launch a rape inquiry into any claims of illicit sex.
Mariah Yeater’s baby – Tristyn Anthony Markhouse – was born on July 6.
Her grandfather, Eddie Markhouse has come forward to insist she is telling the truth.
Eddie Markhouse told Radaronline.com: “I don’t know the whole story. But, from what I understood, she met him at a concert and he sent two security guards down off of the stage to bring her backstage to meet him.
“She’s basically an honest good person. She’s got a big heart. She’s a good kid and she loves this baby.”
Justin Bieber has sold millions of records around the world after first being discovered in 2008 when a talent manager spotted his videos on YouTube.
The singer’s debut album My World went platinum.
Justin Bieber was raised by his mother, Pattie as a devout Christian and says he talks to Jesus and “he’s the reason I’m here”. The singer is said to pray before concerts.
Justin Bieber has been dating girlfriend Selena Gomez since the end of last year but the couple waited until the Oscars in March to make their first public debut together.
