Justin Bieber is back with his Baby Selena Gomez - The Sun

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

He wore a baseball cap with the letter T on it, whilst his girlfriend covered up in a black jacket, white shirt and pink heels.

The pair were at the MTV Voices dinner as Justin picked up an award for his charity work. They posed for a pic with David Hasselhoff who tweeted it to his fans.

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, 20, claims the 17-year-old fathered her baby in a quickie romp backstage.

She said the teen heart-throb told her it was his first time and was "clearly embarrassed" it lasted only 30 seconds.

She wants Justin to take a paternity test and "provide adequate support" for her four-month-old boy Tristyn.

Mariah said 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. Justin has vowed to "ignore the rumours".

He told his 13million Twitter followers he would "focus on what is real" and added: "Judge me on the music! Love yall!"

Mariah's claims could be heard in court next month.

But the teen pop titan has spoken out this week to rubbish claims that he slept with Mariah Yeater and fathered her baby.

He told The Today Show: "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."
