This initiative is part of the Prince's Trust's Tomorrow campaign, which urges employers to recognise young people as tomorrow's industry leaders.
Kelly will mentor 28-year-old Fay Martin, who overcame unemployment with help from The Prince's Trust, to design a home interiors product that will be sold on QVC later this year. Kelly will help Fay launch the product by providing guidance on development ideas and retail concepts.
Other established industry faces taking part in The Prince's Trust Tomorrow campaign include designers Zandra Rhodes and Wayne Hemingway, beauty entrepreneur Liz Earle and chef and food writer Gizzi Erskine.
Kelly Hoppen MBE said "At this time of record-breaking youth unemployment, we need to cultivate young talent and give young people hope. I hope that, by sharing my experiences, I can help young people to pursue their own ideas."
