The 41-year-old television presenter has revealed her 16-month-old daughter Coco is incredibly close with her ex-boyfriend Simon's two-year-old son Eric.

Terri revealed: "Coco and Eric are like this. They are really good friends; we go on lots of playdates. Eric calls Coco his girlfriend, so it's scary. Simon's already warned me, so we will see what happens there but Eric is adorable, such a cute little boy."

And Terri, who is still close friends with the 56-year-old music mogul despite their six year romance coming to end, has also revealed Simon is a "big softie" since he welcomed Eric into the world.

She added: "He's a big softie, especially now he has Eric he has definitely got softer. I think because we didn't have a bad break up and we've always been such good friends.

"We never fell out when we split up, we continued our friendship and he is literally one of my best friends. We just get on really well. And Lauren [Silverman, Simon's partner] is a good friend and we do things all together."

Meanwhile, Terri also opened up about how she achieved her post-baby body, claiming she is the "worst person to ask" for advice on how she stays in shape because she hasn't done any exercise since she welcomed her daughter into the world over a year ago.

She told DailyMail.com: "I'm the worst person to ask [how to stay in shape] because I haven't done any exercise since I had Coco. So I think just running around after her and eating healthily but I literally did my first yoga class today after having the baby. It nearly killed me."
