Amanda Holden, an English actress who is well known for her role as Mia Bevan on Cutting It, claimed that the Girls Aloud singer has not been eating or exercising normally.
“My jaw drops when I see Nadine looking so skinny,” Holden told The Sun.
“She claims she is fine and genetically skinny but I don’t believe she’s eating or exercising normally. She can’t be.”
The Britain’s Got Talent judge added: “I understand the pressure on women in the public eye to stay slim. I hope that away from the spotlight her family can persuade her she needs help. Quick!”
Coyle, 24, has hit back at suggestions over her diet on a number of occasions.
