Princess Kate wows in vibrant green rented dress & Diana’s emerald necklace at Earthshot gala in Boston

KATE Middleton last night wowed US fans as she arrived at the Earthshot Gala in Boston in a £74 rented dress and Princess Diana's emerald necklace.

The Princess of Wales arrived on the green carpet to huge cheers just a day after the Duke and Duchess of Sussex dropped the explosive teaser.

The long-awaited £88million show is set to hit screens in one week's time.

It teased the details of what the couple would share, including Harry saying: "Nobody sees what's happening behind closed doors."

This saw the Duke and Duchess of Sussex apparently dubbed "the Kardashians" by some sources close to Kate and Wills.

There are fears the 60-second clip was deliberately aired to coincide with the Prince and Princess of Wales’ three-day trip culminating in William’s televised £50million Earthshot Prize.

And claimed William and Kate was "blindsided" by the release.

But yesterday the graceful Princess was all smiles as she walked the green carpet in an electric green dress from rental platform HURR by Solace London and necklace from Princess Diana.

Suited Wills waved to the crowds and got a standing ovation as he walked hand in hand with Kate into the MGM Music Hall at Fenway.

Footy ace David Beckham added stardust to the show as he appeared on the green carpet and last night was set to award one of the prizes on the £50million show.

Guests have been asked to wear recycled or borrowed clothing at the eco-bash.

Others on the green carpet included Bond baddie Rami Malek and singer Ellie Goulding.

Earlier in the day she visited the Center on the Developing Child at Harvard University in Cambridge.

In a long blue collared dress she met with academics of the world famous university.

The visit is part of her ongoing work to elevate the importance of the early years to lifelong outcomes.

The Harvard Center has long been a friend of The Royal Foundation and more recently The Royal Foundation Centre for Early Childhood, supporting with past research on the importance of the early years.

Kate was also snapped signing the college’s visitors book - which was signed by her father-in-law- King Charles, back in 1986.

There have been no sightings of Harry and Meghan since they dropped the bombshell preview.

The pair, dubbed the “moaning millionaires of Montecito’, are next expected to appear in public when they visit New York next Tuesday to pick up an award.

Earlier this week, enivronmental campaigner Meghan was spotted boarding a private jet from Indianapolis after attending a female empowerment conference.

It is believed that Harry and Meghan were aware that the trailer would air in the middle of the Wales’s vital three-day trip.
