Shailene Woodley stuns in a see-through black lace jumpsuit at the Earthshot Prize gala in Boston

Shailene Woodley looked fashionable as ever while attending the glitzy Earthshot Prize gala held at MGM Music Hall in Boston on Friday.

The Adrift star, 31 – who’s known for her eco-activism – dazzled in a sheer short-sleeve black lace jumpsuit with a black top and shorts underneath. 

The Earthshot Prize is a charity founded in 2020 by Prince William‘s Royal Foundation. The Prince and Princess of Wales will wrap up their time in America by announcing the winners at the ceremony.

The actress paired her stylish outfit with black heels and wore her brunette tresses in a sleek ponytail. As for glam, the beauty highlighted her stunning features with dramatic lashes and a touch of lipgloss.

Woodley is known for her passionate environmental activism, and has often used her platform to speak up against pollution and climate change.

In 2016 the star was arrested for protesting against the building of a $3.8billion pipeline. The actress livestreamed her demonstration at the construction site of the four-state Dakota Access pipeline for than two-and-a-half hours before she was taken into custody.

In 2019 she partnered with Greenpeace and marine researchers to examine the impacts of plastic pollution in the water. In 2010 she also founded the All it Takes organization, which promotes sustainability. 

The Princess of Wales brought the theme of her husband’s eco-friendly Earthshot Prize to life in spectacularly stylish fashion, when she arrived on the ‘green carpet’ wearing a rented neon green off-the-shoulder gown.

She added plenty of bling to her look in the form of a stunning diamond-and-emerald choker that once belonged to her late mother-in-law Princess Diana.

The dazzling art deco choker – which is believed to be worth more than $15 million – was gifted to Diana by the Queen, who herself inherited it from her grandmother Queen Mary.

Ellie Goulding, 35 – who will be performing at the event – looked ethereal in a long-sleeve white gown belted at the waist.

The singer wore her brunette tresses cascading down in delicate waves. The glamorous beauty accessorized with gold chain earrings and a variety of gold rings on her fingers.

David Beckham, 47, opted for a smart black tuxedo as he arrived solo ahead of presenting an award at the eco-friendly occasion.

David was in high spirits as he arrived for the event, sporting his classic black suit while walked on the recycled green carpet.

The star had previously been in Qatar to attend several of England’s matches during the 2022 World Cup, after his controversial £10 million deal to be an ambassador for the Middle Eastern nation. 

Annie Lennox, 67, showed off her original style in a large red scarf over a purple velvet jacket and striped pants. 

The Eurythmics star finalized the look with violet high-heel boots. 

The musician rocked her iconic bleached pixie hairstyle while flashing a bright smile for the shutterbugs. 

Rami Malek, 41, looked dashing as ever in a black tuxedo and bowtie. He paired the look with a classy watch and black dress shoes. 

The Earthshot Prize gala awards about $1.2 million to each of five winners in the following categories: nature conservation and protection, air quality, ocean revival, waste-free living and climate action. 

It seeks to find innovative solutions that can help repair the planet in the next ten years. 

Prince William was inspired to establish the Earthshot Prize by President John F. Kennedy’s 1962 ‘Moonshot’ challenge, which sought to land a man on the moon within ten years. 

Other guests attending included Billie Eilish, Ellie Goulding, Chloe x Halle musical duo, and Annie Lennox. 

The event will be hosted by Daniel Dae Kim and Clara Amfo. Aside from Prince William and Princess Catherine, presenters include Catherine O’Hara and Rami Malek. 

The Earthshot Prize – and its accompanying TV broadcast – is intended to be one of the greenest televised events in history.

Even before the guests arrive at the gala they will have been given a very green dose of eco-friendly advice and rules to follow, with attendees encouraged to ‘consider their clothing’ for the occasion and opt for ensembles that can be re-used, or have already been purchased second-hand.

Travel plans for guests have also been given environmental updates: all transportation being used with Boston is electric or hybrid and any ‘unavoidable’ flights that were taken have been ‘recorded and the CO2e impacts were calculated and balanced’.

Then, upon their arrival at the event, guests will be treated to a host of ecologically-minded measures, from the plant-focused decor to the vegan and vegetarian-only catering options.

Instead of a red carpet for the stars to walk down, last year’s green carpet is being re-used – and it will be recycled afterwards.

The entryway and the event itself will feature over three acres of plants, including New England-grown evergreen and deciduous trees- ‘all native and grown locally,’ explained Earthshot’s new CEO Hannah Jones, formerly Nike’s first chief sustainability officer.

All the flowers are also grown locally within a 100 mile radius of the MGM Music Hall in Boston. Most are ‘root ball’ plants, wrapped in burlap, to stay as green as possible and will be donated to local community-based organization after the show.

BBC Studios, who are staging the event and won a BAFTA for last year’s show, have flown over just 10 members of staff out of a crew of 150, hiring local firms instead.

No gas lighting will be used with all fixtures being LED battery-operated and charged locally in Massachusetts.
