Downton Abbey is thought to be poised to strike another casting coup with Prince Harry’s ex-girlfriend Cressida Bonas.

The 25-year-old is said to have been in talks with the hit ITV series’ creator Julian Fellowes about a possible role in the next run, and is apparently a huge fan of the period drama, according to the Daily Star.

A source said: “Cressida is trying to break into Hollywood and knows a Downton role would do wonders for her profile, not only in the UK but also the US.

“She met Julian in the run-up to the Golden Globes. While it was a very informal chat, Julian was said to be hugely impressed with her.

“He even promised to set up a meeting with the show’s casting director in the UK to talk about a possible cameo in the next season, which may lead to a more permanent role.”

Cressida has already made her first steps into the acting world by bagging a part in Harvey Weinstein’s upcoming romantic drama Tulip Fever, alongside the likes of Dame Judi Dench, Cara Delevingne and Christoph Waltz.

Harvey predicted: “People will see what a fantastic actress she is. It will be the first of many roles for her.”
