Sting, Sienna Miller, Kate Beckinsale, Rebel Wilson and more attend Monte Carlo Gala 2020

In Monaco last night the glamour of a celebrity gala was a world away from the virtual ceremonies we've become so used to seeing this year - though masks were still compulsory.

Stars including Sienna Miller, Kate Beckinsale, Johnny Depp hit the red carpet at the Monte Carlo Gala for Planetary Health.

The event, hosted by Prince Albert II of Monaco, aims to bring together some of the world’s leading philanthropists, celebrities, decision makers and more in an effort to “address the widening gap between health and environment.” The organisation funds various charities and projects with similar goals.

Sienna Miller was one of the best dressed of the night, opting for an all black look with a striking cut out PVC shoulder collar detail and velvet skirt by Gucci.

Kate Beckinsale wore a glittering white one shouldered dress, which came with its own matching mask.

Pitch Perfect star Rebel Wilson also went for sparkle on the night, choosing a rainbow gown as she and her boyfriend Jacob Busch made their relationship official on the red carpet.

Game of Thrones star Maisie Williams and boyfriend Reuben Selby continued their mission to become young Hollywood’s most fashionable couple, with Williams wearing a rainbow embroidered gown as Selby wore a black and white check suit.

Helen Mirren was a vision in green alongside her partner Taylor Hackford.

Singer Sting was also in attendance, wearing a monochrome black look.

Johnny Depp also attended and kept his mask on for photos, before taking it off for a full length shot.

Of course, Princess Charlene was one of the best dressed of the night in a silver gown alongside her husband Prince Albert II of Monaco.

Bleeding Love singer Leona Lewis also performed on the night, attending in a glamorous off the shoulder gold dress.
