Justin Bieber ruins smart tuxedo by exposing tattoo sleeves

He was so close to looking remarkably dapper at the amfAR gala during the Cannes Film Festival on Thursday.

But Justin Bieber just couldn’t resist putting his expansive collection of body art on display.

The pop star decided to roll up the sleeves of his classic black suit in favour of showing off some different sleeves – the tattoos that cover his arms.

Justin otherwise looked suave in his double breasted jacket, skinny trousers and tie, white shirt and dress shoes.

His sandy locks were slicked into a quiff and he revealed a feeble attempt at a beard.

Perhaps the 20-year-old was attempting to look his best in the hope of impressing his rumoured new love interest Barbara Palvin.

The model was also in attendance at the star-studded event, held at the luxurious Hotel du Cap-Eden-Roc.

Barbara looked breath-taking in a black gown that was floor-length but had a sheer skirt to allow her to show off her long and lithe legs.

The Hungarian born beauty, also 20, was flashing some cleavage too thanks to the plunging neckline of the dress.

Barbara completed her sexy look with some hoop earrings and tied her newly dyed auburn locks into a sleek ponytail.

The pair certainly seemed to be enjoying each other’s company the previous evening at a party on Roberto Cavalli’s yacht.
But after they posed together for a photo backstage at the lingerie show, Barbara quickly denied a romance to Justin’s famously fiery fans, the Beliebers.
