Shelley Conn has admitted she's been left broody by her latest role.
The Mistresses star, who is dating actor Jonathan Kerrigan, plays pregnant career woman Nisha in new ITV drama Marchlands, and her research has made her want her own children.
"It made me quite broody actually, especially being around all those newborn babies!" she said.
"At the time I had two pregnant sisters, one at the later stages of pregnancy, like Nisha, and the other sister was at the very early stages of pregnancy - we weren't really supposed to know she was pregnant."
She continued: "My elder sister who'd already had a child said, 'I really don't like the way pregnancy's often portrayed on TV, so I really hope you get this right', so it was like, 'Oooh, pressure', but it was really helpful because I had these two great points of research."
To prepare for a scene where she's in labour, Shelley did some research online and was surprised by what she found.
"I'm amazed at how many people put their home births on YouTube, but it was great for me. I put all the links on an email and sent them all to Elliot Cowan who's playing my screen husband Mark, so he could get an idea and one morning he arrived and was traumatised by having seen these home births!"
:: Marchlands begins on February 3 on ITV1.
