The 37-year-old actress met the 'Call the Midwife' star when he had a guest role in her show 'Holby City' in 2016 and she's revealed they secretly tied the knot after she left the show in September 2017.

Camilla - who reappeared as Dr. Zosia March for one episode last year and returns for an extended stint this week - told The Sun newspaper's Bizarre TV column: Her character was last seen leaving her husband -- Ollie Valentine, played by James Anderson -- and heading off to work in America. In an exclusive interview, Camilla said: "The break was really nice as I'd been in Holby for four years.

"I wanted to try something else and we also got married. It was a low-key ceremony in London but it was really lovely. It was great.

"It's nice to be back for a couple of months. I love it on 'Holby'."

Camilla's character departed the show when she left her husband, Ollie Valentine (James Anderson), to work in America and the actress teased she's returning with a mystery.

She said: "You find out she is pregnant.

"Viewers won't know who the father is but a handsome American doctor also turns up. Everyone thinks it's his child."

When Zosia and Ollie tied the knot on the show, James revealed a surprising co-incidence - their on-screen wedding aired just a day before he wed childhood sweetheart Rebecca Hibbs.

He tweeted at the time: "Got married last night on BBC One. Now off to get married in real life. #goingforthedouble (sic)"

And the actor has found the similarities between his personal and professional life "weird" and Camilla had had the same experience.

He previously: "Weirdly, we shot the proposal a couple of days after I got engaged in real life.

"There are a few things in Ollie and Zosia's story that strangely mimic my own, and in some ways Camilla's personal life too.

"It's been lovely for us both."
