Sam Quek and her husband were "shocked" to find out they were expecting their second child so soon.
The 'Question of Sport' team captain and her spouse, Tom Mairs, are set to become parents for a second time next year, and after they endured a devastating miscarriage months before welcoming daughter Molly into the world in March, they couldn't believe it when they found out she is expecting again.
Speaking to The Mirror, the 33-year-old former field hockey player, who is 17-weeks pregnant, said: "We were shocked but we’re so excited. But because of our previous experiences, I never like to get too excited until we’ve had our 12-week scan."
Tom added how he believes the Olympian being a twin is the key to her success because she has someone to "compete with" and he hopes it will be the same for their daughter and her unborn sibling.
He added: "We didn’t think it would happen so quickly. I’m actually really pleased we’re going to have two so close together because one of my siblings was just under 18 months older than me and my life was far better having a sibling so close. I also think a lot of Sam’s success is down to the fact that she’s a twin, especially to a boy [brother Shaun], as she had someone to compete with. We’re very pleased for Molly."
Sam - who came back with a Gold for Team GB’s women’s hockey team at Rio 2016 - admitted her little girl will be an "amazing big sister".
The TV star laughed: "She has no idea what’s coming - she’s still too young to understand! But she will be an amazing big sister. She’s so nosey."
Although the pair couldn't be more thrilled to be expanding their brood, Sam admitted she will be "worried" the whole pregnancy after suffering a tragic loss.
She admitted: "You just stop yourself getting too excited in case you get any disappointment. It’s sad because when you get pregnant you should have that joy and elation, like Tom does straight away, but even now I’m constantly worried. I will be for the whole pregnancy. Anything I feel, even if it’s just wind, I think, 'Is everything OK?' Every time I go to the toilet, as a woman, if you’ve had a miscarriage, you will check the tissue for blood. It will never go away and it’s just an unfortunate experience for people who have gone through it. But I think pregnancy is a miracle and part of me is so grateful it’s happened so easily this time."
