Keegan explained: "I met a lady called Jo who was amazing. No-one really talks about surrogacy, it's a bit of a taboo subject. She basically said, 'I've had my own children and I wanted to help other people have children'.
"I couldn't get my head around it at first, but when she told me the stories… it's just amazing."
She continued: "I would never rule it out now, ever. If someone really needed my help I would never rule that out... or if I needed [a surrogate], yeah, 100%."
Keegan added that she is delighted to now be wearing Coronation Street's on-set baby bump.

"It's been round the whole cast," she joked. "But I love it, I've been waiting for that bump for years."
Asked whether the story has made her broody, the 25-year-old replied: "Yeah, I'm always broody anyway - I love kids!"
Coronation Street continues tonight (December 12) at 7.30pm on ITV1.
