Meghan Markle and Prince Harry's children, Archie and Lilibet, could enjoy a "glittering media career" after growing up "next door to film people and celebrities".
Hollywood will be a "massive influence" on the youngsters, who are going to be "American through and through", claims author Tom Quinn.
He also said it is "extremely unlikely" we'll see Archie and Lilibet taking part in the same activates as other young royals, with Tom claiming it's "the way Meghan wants it".
"I think they're much more likely to have a glittering media career than a glittering royal career, just because that will be the massive influence, you know, they're living in America, they're living next door to film people and celebrities.
"We know that from other film people that their children might struggle a bit but you always find that they're involved at some level with Hollywood if that's where you grow up, that's what you take in."
Speaking on Newsweek's The Royal Report podcast, Tom said people shouldn't hold out hope that Archie and Lilibet will return to the UK.
"I think it's extremely unlikely they'll suddenly come back and take part in the sort of activities that younger royals take part in over here, you know, they're going to be American through and through and I think that's the way Meghan wants it."
Meghan and Harry moved to Montecito, California, just a few months after stepping back from the Royal Family.
Living in their nine-bedroom home, the couple now count US TV royalty such as Oprah Winfrey and Ellen DeGeneres as their neighbours and friends.
Meghan says her new home makes her "feel free" and is "calm and healing" to live in the luxury mansion in the gated community in Santa Barbara.
In an interview with The Cut, the 41-year-old gushed over her 18,000-square-foot property, where she lives with her family.
The property boasts nine bedrooms and 16 bathrooms, as well as a tennis court, tea house and two-bedroom guest house.
There's also a chicken coop, a pool and a pool house, and two palm trees joined together at the bottom of the garden.
