It was the name of Hear'Say's first single, and Myleene Klass certainly looked pure and simple in a low-cut white dress Monday morning on ITV1's Lorraine.

The Heart FM presenter was on the couch speaking to Kate Garraway - covering for Lorraine Kelly - about her role as a Save The Children ambassador for the charity's No Child Born to Die campaign.

But after discussing the trip to her Filipino homeland, Myleene made it clear there was no chance she'd get the Popstars-winning band back together, unlike a number of her other musical contemporaries.

Wow! Myleene Klass looked fantastic in a pure white dress on Lorraine Monday morning

Mentioning The Big Reunion - the TV series that sees the Honeyz, Liberty X, 5ive, B*Witched, Atomic Kitten and 911 reform ahead of a special arena tour - Kate asked if Hear'Say would make a comeback.

Laughing at the thought, Myleene replied: 'I just can't imagine it - sing Pure And Simple on loop? It was nice and a great time in our lives but to relive it wouldn't be the same.'

'I'm a bit too old to jump around in Lycra now!' She continued, 'it was a good time in that era.'

But rather than talk about her pop background, the mother-of-two was there to discuss the cruel reality of the present, concerning the millions of children dying from preventable diseases.

'Just a few hours on the plane you might as well be on another planet,' Myleene said about her trip to the Philippines capital Manila, where she was shocked to find the harsh environment mothers and children are forced to live in.

Highlighting the problems with using formula over breast milk, the 34-year old said, 'It cost them twice their rent to feed one child and they can't feed the rest so they have to water it down because they can't afford it.'

'On top of that the water's filthy and they can't sterilise the bottles.'

Myleene's mother - who is a nurse - moved to England before she was born, and now the classical musician sees the irony of sending medical personnel back.

She said, '[we need to] educate people within the community, get their own midwives and godmothers out there speaking to the women' to encourage new mothers to breast feed within the first hour after giving birth to help protect them from infection.
