The 21-year-old star, who is the daughter of activist Bob Geldof, will present the new six part series, OMG! Totally Peaches, that will be filmed in front of a live audience.
Geldof will be joined by professional experts who will help the show's guests with their problems.
Guests will share their problems through a VT screen and the panel, Peaches and the audience will help solve them.
Geldof said: 'I'm so excited to be presenting this show and getting to meet and interact with the ITV2 audience and the guests. I can't wait to find out what's really on the minds of young people in Britain today.'
