Who does Dermot play in BBC drama The Split?

Speaking ahead of the first episode, Dee revealed that her hubby has landed a role in the final series.

He will feature in a daytime TV segment that airs as part of one of the episodes.

Dermot is such a huge fan of The Split anyway, he was so over-excited to be part of it.

Dee said: “You never want it to feel nepotistic, but it was scripted that one of the characters is interviewed on a breakfast TV show.

“It was one of those funny things where I felt it’d be so weird to get someone else!

“So I said: ‘I might have someone I know who’d be up for this!'” she added.

“We’ve got some really good cameos this season, from Lily Cole to Tom Rhys Harries to Lindsay Duncan, it’s amazing!”

How long has Dermot O’Leary been married?

The This Morning presenter tied the knot with Dee in 2012 after 10 years of dating.

And the couple – who are parents to a little boy named Kasper – have one of the strongest marriages in showbiz.

Earlier today, Dermot took to Twitter to wish Dee good luck with the first episode of The Split.

Sharing her tweet about the show, he spoke of his pride for his wife.

“Happy show day @deekoppang!” he exclaimed.

“V proud of you. The first ep is a cracker you won’t be disappointed. But there will be tears… best bring some gin for the journey,” he concluded.
