The Loose Women panellist said she could relate to how the couple are feeling, explaining that she went to a "strange place" when she had a miscarriage.
Speaking candidly to her co-stars Christine Lampard and Jane Moore, Nadia said: "I chose to come back from the hospital and have [the miscarriage] at home. It wasn't pleasant it was long and awful, Mark was with me.

"Mark was in real bits, I went to this strange place where I phoned everyone up, my family live next door. I rang everyone up and said 'get me some chickens and potatoes, I'm going to do a roast dinner.'"
Nadia went on to say she was "in shock", adding: "This poor man [Mark] was just reeling. But that was my way, in a microcosm, it's a similar kind of thing, I wasn't in my right mind when I did that. I was a bit in shock."

The mum-of-two continued: "I often think about that, it must have really hard for Mark because I just did what I needed. We were in the same position even though he hadn't physically done it."
Jane asked Nadia if cooking the meal was a "form of distraction" from her grief, to which she responded: "I was exhausted, I should have rested, but I wasn't going to let Mark tell me, I just wonder... if a bit of that comes into it because they're reeling and in shock."
Nadia and Mark are parents to two daughters
Nadia isn't the only star to share her own personal story in response to Chrissy and John's devastating news; Gary Barlow, whose daughter Poppy was delivered stillborn in 2012, publicly reached out to the couple on Twitter, writing: "No words can make the pain any easier."
Meanwhile, Amanda Holden took to the comments on Chrissy's Instagram post to reveal how she coped following the stillbirth of her son Theo in 2011. One of Chrissy's fans sent the star a very uplifting message, writing: "In Lebanese culture we believe babies like Jack are angels that God selectively chooses to watch over you. Sending you light. "
Amanda was quick to react to the comment and said: "This is how I dealt with my loss x."
