Rod Stewart's ex-wife Rachel Hunter has dismissed her 'yummy mummy' label, insisting she's horrified to think her son's friends might lust after her. The 37-year-old model and mother of two recently starred as a pole dancer in a music video for rock band Fountains Of Wayne. But despite the sexy role, Hunter admits she's uncomfortable being a pin-up for her children's pals. She says, "As a mother, you don't think of your kids' friends fancying you. But it's completely that MRS ROBINSON thing. I think older women look a lot younger now." Hunter has two children with Stewart, RENEE and LIAM.
