Beautiful in blue! Priyanka Chopra dazzles at star-studded UNICEF 70th anniversary bash with David Beckham

A cavalcade of celebrities rolled across the sky blue carpet when Unicef celebrated its 70th anniversary on Monday night.

Priyanka Chopra struck a particularly chic figure among the famous names who'd gathered at the United Nations headquarters in New York City.

The 34-year-old posed alongside a besuited David Beckham, who presented her with Unicef Goodwill Ambassadorship during the evening's festivities.

Pear-lined pleated short sleeves mirrored the pleated bottom section of her navy, hammered satin Prabal Gurung dress.

Tightening about her enviably slim torso, the bias-cut outfit featured a hem that'd been cut off high enough to showcase the Quantico star's navy stilettos.

Meanwhile, Mr Posh Spice, a Unicef Goodwill Ambassador since 2005, garnished his evening wear with a pin advertising the organisation.

The 41-year-old's pinstriped suit was a colour similar to that of the Baywatch actress' dress, clashing against his white dress shirt.

Almost indiscernible green and pink patterns swirled about his burgundy tie, and his hair was slicked severely back.

Orlando Bloom, who'd become a Unicef Goodwill Ambassador in 2009, used a white pocket square as a pop of contrast against his dark suit.

The zaffre dress shirt the 39-year-old was wearing had a bit of sheen, and he'd spiked up his blonde hair.

Though his girlfriend Katy Perry became a Unicef Goodwill Ambassador three years ago, she didn't appear to have accompanied him on Monday. 

Glinting black dress shoes rounded out the The Lord Of The Rings actor's ensemble, and he'd undone his top button, going without a tie.

Fan favourite: Orlando addressed the audience from behind a podium

Jackie Chan was made a Unicef Goodwill Ambassador 12 years ago, and looked almost like a priest, wearing a black Nehru-collared top over a white T-shirt.

Black-rimmed spectacles matched the 62-year-old's slacks and shoes, and he squatted to be level with wheelchair-using Juan Carlos Morán Menjivar.

As a YouTube video uploaded by Unicef described, Menjivar lost his arms and legs when he stepped on a landmine buried during the Salvadoran Civil War.

Action star: The martial arts film star showed some of his moves at the celebration

Unicef, as he recalled, enabled him to travel away from home in order to obtain prosthetic legs. He also underwent rehabilitation.

A committed painter, whom the video shows holding the brush between his teeth, he's since married and graduated law school.

Inasmuch as Unicef were billing the event as a 'children's takeover' of the building, it was only fitting that Millie Bobby Brown should hostess the fête.

Taking the job seriously: Her duties as a compere included speaking solo at the blue and white podium

Adorable: The 12-year-old arrived in a turtlenecked pale pink dress, embellished with pink, purple and green floral patterns and some rose-shaped black trim

Face to face: Millie and David talked face to face on the stage

Unicef have posted a YouTube video about the 14-year-old, noting the Mediterranean crossing he and his mother made to Greece.

Now, coming to the stage: Brown threw open her arms as Beckham walked on

Dynamic duo: The pair of them at one point addressed the crowd together

His father in Iraq and one of his sisters still in Syria, the 14-year-old and his mother have since settled in the Bavarian town of Hof.

Not only did she take the blue and white podium, speaking solo, but her compere duties also involved sitting down to interview the erstwhile footballer.

She also had a chance to share a warm hug with Chopra, one of two Bollywood stars to become Unicef Goodwill Ambassadors (the other being Amitabh Bachchan).
