Pregnant Sheridan Smith shows off growing baby bump on date night with fiance Jamie Horn

Sheridan Smith is pregnant with her first child and proudly showed off her growing baby bump at the opening night of Pretty Woman: The Musical in London last night.

Dressed in all black and some Gucci boots, the Cilla actress was glowing as she cuddled up to her fiance Jamie Horn.

Sheridan shared a picture of Jamie and herself cradling her bump, and pointing out the fact there was a lightbulb above Jamie's head, captioned it: "By looks of this pic, Jamie had a eureka moment last night!"

She added another picture of herself, and revealed her unborn "tiny dancer" baby hadn't stopped moving during the show.

She wrote: "Great night @prettywomanmusicaluk what a show, thank you for having us! The baby was kicking throughout @jammyprod so proud!

"Can’t wait to watch again once our tiny dancer has arrived! Xx"

Sheridan and Jamie pair are due to become parents in just a few weeks.

She first sparked pregnancy rumours when she took to Twitter, in October last year, to say: "About to set sail for 4 days, wish me luck with my morning sickness."

She then confirmed the news to audience members onboard the cruise ship, saying : "I've got a baby on board."

In the same performance, she was also talking about morning sickness again.

She said: "I've got buckets in each wing and trainers so I can run. I'm very out of breath. I've got all these new symptoms, so sorry!"

She eventually publicly confirmed the news on Instagram when she shared a picture of a baby blanket and teddy bear embroided with "Baby Smith-Horn".

Sheridan recently confessed they can't wait to meet their newborn with a picture together on Instagram, and wrote: "Us pretending to be responsible adults ready for whatever life throws our way."
