First image of Bieber 'love child'

Claims ... Mariah Yeater and her four-month-old baby Tristyn - who she says is Justin Bieber's son

THIS is the first image of the baby at the centre of Justin Bieber's "love child" scandal.

Fan Mariah Yeater, 20, alleged earlier this week that Bieber is the father of her tot.

And she claims the evidence can be seen in four-month-old Tristyn Anthony Markhouse Yeater's POUT.

Last night it was reported the star will take a paternity test in LA this month after denying he is the dad.

Mariah, 20, claims the child was conceived during a quickie in a backstage bathroom at one of his concerts.

She claims the resemblance between the superstar singer and her son is remarkable.

In this sensational picture she can be seen holding the fair-haired child in a park in Los Angeles.

She was reported as saying in the media: "Look, just look at his mouth.

"Look familiar? I pray that Justin sees these photos, looks at Tristyn and knows in his heart that this is his child and our child. It's going to be a nightmare for all of us if he keeps denying it.

Girlfriend ... Bieber with current squeeze Selena Gomez

"I just want what is right for our son, I feel terribly hurt that we have been abandoned and none of my calls to Justin were returned."

Despite the lurid claims, Justin's girlfriend Selena Gomez stood by him as he scooped an award for his charity work in Belfast last night.

The squeaky-clean pop star, who has dated 19-year-old Disney starlet Selena since December, was with her at the MTV European Music Awards yesterday.

Justin once promised his mum he would "stay pure" until he met Miss Right. And in February he said: "I don't think you should have sex with anyone unless you love them."

But Mariah claims that during one of his shows a security guard asked her if she wanted to meet Justin backstage.

She claimed: "Immediately, it was obvious we were mutually attracted and we began to kiss."

She said Justin suggested they find a "private place". She added: "He told me he wanted to make love to me and this was going to be his first time."

They went into a bathroom where, according to Mariah, Justin made it clear he wanted sex in much cruder language.

She said: "I asked him to put on a condom for protection but he insisted he did not want to. He said because it was his first time he wanted to feel everything."

Mariah added Canadian Justin immediately dressed after the brief bunk-up and snubbed her request to see him again.

She claimed she tried in vain to contact him when she became pregnant and insisted Tristyn could have no other dad.

She wants Justin to take a paternity test and "provide adequate support" for her son.

But the teen pop titan told The Today Show this week: "Never met the woman.

"I'd just like to say, basically, that none of those allegations are true. I know that I'm going to be a target, but I'm never going to be a victim.

"It's crazy. Every night after the show I'm gone right from the stage right to the car, so it's crazy that some people want to make such false allegations.

"To set the record straight, none of it is true."
