ONLOOKERS were amazed at how 39-year-old Dannii Minogue slimmed down dramatically so soon after giving birth to her baby boy.
But her shock weight loss wasn't gym-related, and behind closed doors the other Minogue sister was a "car running without petrol".
Doctors eventually diagnosed her with a thyroid problem which, coupled with appendicitis, left the star with barely enough strength to pick up her newborn.
Struggling with the condition and stress, Minogue quit her judging role on the X-Factor to take care of herself and son Ethan.
"My thyroid stopped working and I had appendicitis," she revealed to The Daily Mail.
"Leading up to that I was getting thinner and thinner, and stressing because I didn't know what it was."
Beneath the surface of what many thought was a "yummy mummy" workout regime, the turmoil put pressure on Minogue's relationship with Kris Smith.
"It got to the point where I thought, 'This cannot be normal'," she said.
"Poor Kris. He was thinking after getting through the pregnancy and the baby that everything would be just fine and he couldn't work out why I wasn't well.
"It was bloody difficult."
