Bieber a daddy?……not with girlfriend Selena….

He is currently dating pop sweetheart Selena Gomez, but the 19-year-old might not be happy with recent reports about her beau Justin Bieber.

A 20-year-old woman is said to have filed a lawsuit against the teen pop sensation alleging he is the father of her three-month-old baby, Radaronline.com have reported.

According to reports the California woman named as Mariah Yeater is asking the Baby singer to take a paternity test.

The website reports that Star magazine have obtained the court papers, which are said to have be filed late October, making the request.

According to the website Ms Yeater asks for Bieber ‘to provide adequate support for my baby.’

It has been reported the woman claims she had sex with the underage star on October 25 last year when she was aged 19-years-old, he was aged 16-years-old out the time.

That would mean under California law that he was underage and if the claims turn out to be true Ms Yeater would be guilty of statutory rape of a minor.

According to the website a hand-signed affidavit has been reviewed and  claiming that Yeater was invited backstage by bodyguards after Bieber’s performance at the L.A. Staples centre.

It reports that after describing meeting the singer Yeater wrote in the affidavit: ‘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 to go with him 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.

‘We went inside and immediately his personality changed drastically. He began touching me and repeatedly said he wanted to f*** the s*** out of me. At the time I asked him to put a condom for protection, but he insisted that he did not want to.’

‘In his own words, he said that because it was his first time he wanted to feel everything.’

She is said to have described the intercourse as ‘brief’.

A court hearing is said to have been set for December 15.

According to TMZ a spokesperson for the star said: ‘While we haven’t yet seen the lawsuit, it’s sad that someone would fabricate malicious, defamatory, and demonstrably false claims.’

Justin 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.

In February this year Justin, who is a Christian, spoke out about per-marital sex in an interview with Rolling Stone magazine and said: ‘I don’t think you should have sex with anyone unless you love them.’

Justin has vehemently denied the claims.
