The former Pussycat Doll will also be sitting on The Ice Panel alongside former judge Karen Barber, who has worked as a coach on the show for the last two years.
Ashley, who will be bringing a dance/performance critique to the ITV1 programme, said: "I'm beyond excited to be joining Dancing On Ice as a judge, to work alongside Torvill & Dean is such an honour, they're absolute legends.
"We've got some fantastic names lined up to skate this year and I can't wait to see their routines on the ice."
Karen, who will continue to coach the contestants, added: "We have an absolute wonderful group of celebrity skaters this year who have been training so hard to ensure they deliver on the ice for the viewers and of course us judges.
"I'm thrilled to be on the judging panel for 2013 and I look forward to an exciting and interesting series"
Acid-tongued Jason Gardiner is also returning as a judge after taking a year off, and Robin Cousins will complete the line-up.
