That’s one way to pacify him: Justin Bieber s.u.cks on a b.a.by’s dummy as he displays bizarre behaviour on night out in St Tropez

Justin Bieber showed his slightly more eccentric side when he refused to be parted with his pacifier during a night out in St Tropez on Thursday.

The 22-year-old was pictured sucking on the baby’s dummy in a playful fashion while wearing glasses and a baseball cap.

Heading out with his pals, Alfredo Flores and Nick DeMoura, Justin displayed the hint of a smile.

Though he may have struggled to join in the conversation as he didn’t remove it from his mouth.

The singer wore a rather odd combination of clothing but managed to pull it off in his own unique way as he kept a relatively low profile.

He wore an oversized cream sweater with baggy blue shorts, worn over a sporty pair of black leggings.

Completing his look with a pair of white Adidas trainers, he displayed a host of inkings on his arm as he made his way into the venue.

The singer appears to have been busier than ever.

On Thursday evening, he took to Twitter to write: ‘My #justmojis come out tomorrow @AppStore.’

A step back in time: That pacifier stayed in his mouth as he continued to look at the sports cars

The night before, he was pictured enjoying a night out with British singer Rita Ora, before climbing into his car with a busty brunette.

Last month, Justin wrote a lengthy post to his Instagram account about why he has asked his fans to stop asking him for photos.

He wrote: ‘Years ago it was impossible to even take a picture at anytime not everyone was accessible to a camera now everyone has a camera phone and now it’s just a different thing.

‘If you think setting boundaries is being a douche I’m the biggest douche around but I think it’s smart and will be the only way I last.

‘I wanna enjoy life and not be a slave to the world and their demands of what they think I need to do!!

‘I love the fact that I am able to make people happy but cmon if you truly were in my position you would understand how tiring it is.

‘I’m going to keep making decisions I feel are fit for my growth and no human being will make me feel bad for it.’
