PRINCESS Kate and Prince William will experience a star-studded US tour later this week featuring a string of big names – but not Meghan Markle or Prince Harry.

The three-day international trip is their first since becoming the Prince and Princess of Wales.

It culminates at the MGM Music Hall on December 2 for the Earthshot do, described by one insider as Wills’ “Super Bowl” moment.

Singer Billie Eilish will headline the show, with further performances from Annie Lennox, Ellie Goulding and Beyoncé proteges Chloe x Halle.

Actor Rami Malek, who played Freddie Mercury in biopic Bohemian Rhapsody, and Schitt’s Creek star Catherine O’Hara will present awards, and broadcaster Sir David Attenborough will voice the show’s opening.

Also on the glamourous guestlist will be presenter Clara Amfo, director Daniel Dae Kim, and The Fault in Our Stars actress Shailene Woodley.

But two Statesiders will be notably absent – despite hosting an event on the East Coast just days later, it is understood.

Harry and Meghan are attending the Ripple of Hope gala in New York on December 6 to accept an award for taking a stance against “structural racism” within the Royal Family.

The Duke and Duchess of Sussex, who accused an unnamed royal of raising “concerns” about the colour of their son Archie’s skin, are not expected to join William and Kate at Earthshot, nor during the rest of the Wales’ tour.

Sources say Wills sees Earthshot, his worldwide environmental competition, as part of his increasing “global leadership” role and he won’t be “distracted” by the California-based pair.

“The prize has become the prince’s Super Bowl moment of the year, and he looks forward to continuing to use the platform each year to shine a light on some of the most impactful projects doing amazing things around the world to save our planet’s future,” one said.

Another told The Telegraph: “The Palace team are highly cognizant of Meghan and Harry, but equally, they’re not scared of their shadows on this.”

During the rest of their trip, William and Kate will attend a special event with the Mayor of Boston, Michelle Wu.

Kate will also visit the Centre on the Developing Child at Harvard University, which works with her Centre for Early Childhood.

While her husband will visit the John F Kennedy Presidential Library and Museum with Caroline Kennedy, the former president’s daughter.

The prince and princess are said to be “hugely excited” about their engagements and see them as a key in forging their own paths as senior royals.
