Lord Ivar Mountbatten, the King’s second cousin, will star on the third season of The Traitors US, it has been announced.

The farmer, geologist, businessman and first openly gay member of the extended British Royal family will take part in the popular reality series hosted by actor Alan Cumming.

The show, set in Ardross Castle in the Scottish Highlands, takes a similar format to the BBC psychological series hosted by Claudia Winkleman, but features celebrities instead of members of the public.

Lord Mountbatten, 61, will star alongside Sam Asghari, the estranged husband of Britney Spears, as well as Vanderpump Rules star Tom Sandoval and Selling Sunset’s Chrishell Stause.

It will see the players divided into the “faithfuls” and a smaller group of chosen “traitors” – whose goal is to eliminate the other contestants and win up to $250,000 (£195,785) themselves.

British viewers can watch it on American streaming service Peacock.

Lord Mountbatten is the son of David Mountbatten, the late 3rd Marquess of Milford Haven, and Janet Mercedes Bryce.

Through his father, he’s a second cousin of the King and a first cousin once removed of the late Duke of Edinburgh.

He was married to Lady Penny Mountbatten from 1994 to 2011, with their wedding being attended by Prince Edward and his now wife Sophie, Duchess of Edinburgh.

Lord Mountbatten and his former wife had three daughters, but he later came out as gay and tied the knot with James Coyle, an airline cabin services director, eight years after an amicable split with his wife.

She reportedly walked Lord Mountbatten down the aisle in 2018, and though not a working royal, he is the first member of the King’s extended family to have a same-sex marriage.

His stint on The Traitors US will not mark his first reality appearance, however, as he has also taken part in the ITV shows The Queen and her Cousins with Alexander Armstrong in 2021 and Keeping Up with the Aristocrats in 2022.

The show has previously seen famous British faces take part, including former House of Commons speaker John Bercow and Love Island winner Ekin-Su Culculoglu, who both featured in the second series.

Fellow contestant Asghari, who was listed as an actor in the promotion for the upcoming series, split with pop star Spears in 2023, with the couple citing “irreconcilable differences” in their court filings.

They got married at a star-studded ceremony at the US singer’s home in Los Angeles in June 2022 after meeting on the set of the Slumber Party music video in 2016.

Their wedding was attended by high-profile celebrities including Madonna, Selena Gomez, Drew Barrymore and Paris Hilton.

Also taking part in the third series are RuPaul’s Drag Race winner Bob the Drag Queen, The Biggest Loser trainer Bob Harper, Summer House star Ciara Miller and WWE wrestler Nikki Garcia.

Other contestants include Zac Efron’s younger brother Dylan, Survivor competitors Carolyn Wiger, Jeremy Collins, Rob Mariano and Tony Vlachos, Real Housewives franchise stars Dorinda Medley, Robyn Dixon, Dolores Catania and Chanel Ayan, former The Bachelor spin-off stars Gabby Windey and Wells Adams and Big Brother US version stars Britney Haynes and Danielle Reyes.

Cumming revealed the cast in a video on YouTube, where he was seated in front of a fire and wearing a yellow tartan suit.

He said: “This is sure to be the most treacherous season yet.”
