The Prince and Princess of Wales reportedly have "no plans" to meet up with Prince Harry and Meghan Markle - despite both couples visiting the US east coast in the space of days.
William and Kate are due in Boston from Wednesday for a three-day trip culminating on Friday with the prince’s “Super Bowl” moment – the staging of the awards he founded to discover and scale up environmental solutions to repair the planet.
Just days later next Tuesday, Harry and Meghan will be just 200 miles away in New York City where they will accept an honour at the Robert F. Kennedy Ripple of Hope Awards.
The estranged couples were last seen side by side in the aftermath of the late Queen's death and at her funeral in September.
But despite their close proximity next week, the Daily Mail reports there will be no sign of the brothers and their wives catching up.
Meanwhile, the Telegraph reports that a source says William and Kate's team is 'highly cognisant' of Meghan and Harry they are "not scared of their shadows on this".
It comes after it was revealed earlier today that singer Billie Eilish will lead a stellar line-up for William's Earthshot Prize awards ceremony on Friday.
She will headline the entertainment, which includes Annie Lennox, Ellie Goulding and Beyonce proteges Chloe x Halle, performing at the MGM Music Hall in Boston.
A royal source said: “The prize has become the prince’s Superbowl 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.”
The Earthshot Prize is in its second year and William spoke about the project with South Africa’s President Cyril Ramaphosa earlier this week during his state visit to the UK.
Among the 15 finalists vying for £1 million awarded to each of the five category winners are a cleaner-burning stove initiative in Kenya and a bubble barrier made in the Netherlands to prevent plastics from entering oceans.
Broadcaster Sir David Attenborough, a supporter of the Earthshot Prize since its inception, will voice the opening of the show while Oscar-winning actress and Earthshot judging panel member Cate Blanchett will narrate a look back at the 2021 winners.
Actor Rami Malek, who played singer Freddie Mercury in the biopic Bohemian Rhapsody, will present an award as will actress Catherine O’Hara, who starred in the film Home Alone, and environmental activist and actress Shailene Woodley.
William and Kate are also keen to meet members of many local communities during their visit to a city famed for its Irish community, sporting heritage and history.
The couple is said to be excited about their first international trip since becoming the Prince and Princess of Wales, titles with a long history, but they are keen to forge their own paths.
During their visit, William and Kate will attend a special event with the Mayor of Boston, Michelle Wu, and the prince will visit the John F Kennedy Presidential Library and Museum with Caroline Kennedy, the former president’s daughter,
The prince and princess will learn about the work that local organisations are doing to mitigate the risk of rising sea levels in Boston, and when they tour the Greentown Labs, in the nearby town of Somerville, will get an insight into the development of innovative green technologies.
At the premises of Roca, a non-profit organisation supporting disadvantaged young people, they will hear about the issues they face and Kate, who launched the Royal Foundation Centre for Early Childhood in 2021, will visit the Centre on the Developing Child at Harvard University.
