Singer-turned-reality TV show judge Dannii Minogue is receiving treatment for an under-active thyroid which caused her to shed weight after giving birth.
The Australian star had her first child, son Ethan, last year, but shortly after leaving hospital she fell ill and suffered a bout of appendicitis.
She spent months believing her subsequent tiredness and rundown state was a consequence of her new role as a mum, but she was eventually diagnosed with a thyroid condition.
And she's confessed her health issues even took their toll on her relationship with former rugby star Kris Smith.
Minogue tells Stella magazine, "Yes, that was a hard time for me. I was physically unwell and that takes its toll on everything. My thyroid stopped working and I had appendicitis. Leading up to that I was getting thinner and thinner, and stressing because I didn't know what it was.
"Normally you put on weight if you have an under-active thyroid. But there is a percentage of people that have it reversed. It was very hard to concentrate, you can't sleep, and I got very weak. They explain it to you as running a car without petrol.
"I was finding it hard to pick up Ethan and I was thinking, 'I'm a new mum, I know I'm tired but surely it can't be this hard?'. When you've just had a baby you think it must be normal tiredness. But it got to the point where I thought, 'This cannot be normal'. 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."
Asked if the couple is planning to extend its brood, Minogue replies, "Yes, but honestly until I get my health back on track it's not a possibility."
The airline industry has presented its vision for the future of check-in security, including hi-tech colour-coded scanning corridors.
Passengers will be able to keep their shoes on and their bags in their hand - toothpaste, nail clippers, laptops and all - as they pass through the "checkpoint of the future".
Under a mock-up checkpoint on display at the Aviation Security World Conference in Amsterdam, passengers are guided into one of three corridors upon presenting their passports: blue for frequent travellers, purple for normal passengers and orange for those deemed to require enhanced vetting.
People do not have to empty their pockets, remove any of their clothing or subject themselves to pat-downs before walking through a 20-foot tunnel that scans metals, liquids, laptops and other potential dangers one by one.
International Air Transport Association chief Tony Tyler said: "We spend too much time on the 99.9% who mean us no harm, when threat detection surely should be focused on those with greater potential to do damage.
"By making our checkpoints smarter, and using 'known traveller' programmes, we can give everybody a baseline level of security ... and in the end get everybody through security much faster."
The concept faces technical and financial hurdles, and is likely to be opposed by people who object to profiling or believe passing through body scanners violates their privacy. But it indicates the direction the industry hopes to go, Mr Tyler said.
He argued the "risk-based approach" is not the same as profiling, since it does not use ethnic or religious data. It relies partly on pre-flight information submitted by passengers, partly on biometric scans and data stored in passports, and partly on human observers who would have the discretion to choose a more rigorous scan for someone acting suspiciously.
US Transport Security Authority (TSA) chief John Pistole said the checkpoint of the future idea parallels the TSA's own new emphasis on "risk-based security".
"It's an idea clearly worth consideration as technology develops," he said. "Segmenting the passenger population for different levels of security screening is exactly what we're pursuing."
Bono has paid tribute to the late Steve Jobs describing him as the "hardware software Elvis" and a man "only interested in doing truly great things".
Apple's pioneering former chief executive, who gave the world revolutionary computers, iPhone and iPods, died on Wednesday after a lengthy battle with pancreatic cancer.
U2 singer Bono added his voice to the many tributes paid by world leaders to the 56-year-old technology wizard.
He recalled how aside from his impact on technology and culture, he had helped improve the lives of people in Africa by supporting his (RED) initiative, and how he was a devoted family man.
"What made Steve Jobs truly great is that he was only interested in doing truly great things. He was bored by an easy ride or easy profit," said Bono. "In a world littered with dull objects, he brought the beauty of clean lines and clear thought. This rhyme of intellect and intuition could be applied to a wide range of subjects from the US education system, to sculpture, to the fight against HIV/AIDS where his support of (RED) literally transformed the lives of two million people in Africa.
"He changed music. He changed film. He changed the personal computer and turned telephony on its head while he was at it."
US President Barack Obama said that "the world has lost a visionary," while Bill Gates, Jobs's friend and founder of rival Microsoft said his impact would be "felt for many generations to come".
Devotees of Apple have laid floral tributes outside the computer guru's home in California's Silicon Valley, showing he had a popularity equal to that of many rock stars.
Bono continued: "Steve told me as proud as he was of Apple and Pixar, his real pride was his family. He was a thoughtful and tender father, and loved nothing more than hanging out in the house with his belle Laurene and the kids.
"I already miss him - one of a very small group of anarchic Americans who through technology literally invented the 21st century. We will all miss the hardware software Elvis."
Almost a quarter of Britain's children will be left in poverty by the end of this decade because of the Government's tax and benefit changes, a think-tank is warning. Drops in family income are set to drive up poverty by about 600,000 children and 800,000 working-age adults, the Institute for Fiscal Studies (IFS) report says.
The Universal Credit will lift around 450,000 children and 600,000 working-age adults out of relative poverty - defined as living in a household on less than 60% of average income - by 2020/21.
But the IFS said the positive impact of the new system - to be introduced in 2013 - will be outweighed by other tax and benefit changes.
Its forecasts show 3.3 million children, a quarter of the UK's child population, will be in relative poverty by the end of the decade, compared with 2.5 million children (19.2%) now.
This would mean the Government missing by a wide margin the legally-binding targets in the Child Poverty Act, which stated no more than 5% of children should be in absolute poverty and 10% in relative poverty by the end of the decade.
James Browne, one of the authors of the report, said: "Even if there were an immense increase in the resources made available, it is hard to see how child poverty could fall by enough to hit this supposedly legally-binding target in just nine years."
A Government spokesman said the IFS had not fully considered the behavioural changes expected to result from welfare changes and reforms to the education system.
He said the reforms would encourage people into work - many for the first time.
"Over the last decade billions of pounds have been moved around the tax and benefit system in an attempt to address poverty," he said.
"This has had the perverse effect of trapping thousands of families on benefits while income inequality increased to its highest ever level.
"It is clear that sticking with the status quo which has had no meaningful long-term effect on poverty projections is not an option."
But children's groups described the report as "devastating".
Alison Garnham, chief executive of Child Poverty Action Group, said: "The Government must accept that you cannot fight poverty or improve life chances by making the poor poorer."
Bob Reitemeier, chief executive of the Children's Society, said: "We are particularly concerned that the proposed cap on benefits will cut support to more than 200,000 children and potentially make 82,000 children homeless."
