She has looked after the offspring of celebrities and sportsmen all over the world but Australian Angela Jacobsen is poised to become a household name herself.
The former nanny, who spent 18 months caring for Madonna's adopted son David Banda, is about to publish her second childcare book, start work on two new parenting TV channels in Singapore and is in talks about starring in an Australian version of the TV show Supernanny.
Originally from Victoria and now based in Sabah, Malaysia, Ms Jacobsen is in Perth to launch her book Baby Food at the State Library next month.
Although her days of globe- trotting from private islands to Indian palaces with the Material Girl are over, Ms Jacobsen said she looked back with fondness on an "amazing experience".
"On reflection, I realise how incredibly well-grounded Madonna was," she said. "She's a strong, independent woman and taught me I could achieve anything."
Ms Jacobsen said when her contract was up and she was due to take a holiday, it was time to move on. "Obviously there are a lot of perks - you don't get given designer clothes by the average Australian family - but I knew I could earn the same working for a regular family without all the stress," she said.
