The former glamour model and mum-of-three, who previously won the title back in 2007, beat the likes of Amanda Holden, Chloe Sims, Danielle Lloyd and Holly Willoughby.
Price, 33, said: "Being a mum is one of the most rewarding jobs in the world but it can also be very hard work, especially juggling a busy career with three kids!
"Even when you have friends and family to support you, it makes a huge difference to hear someone say you're doing a good job, and winning 'Celebrity Mum of the Year' for the second time feels like a huge triumph especially because it's chosen by the public."
Mark Segal, director of marketing at Foxy Bingo, added: "We are delighted to announce Katie as the winner of Foxy Bingo 'Celebrity Mum of the Year' 2012. She is undoubtedly one of the UK's biggest stars and manages to juggle this with being a hands-on mum to all three of her children.
"She is a wonderful role model for mothers faced with the difficulties of juggling work and motherhood especially with the challenges she has faced with Harvey, and we at Foxy Bingo congratulate her wholeheartedly on winning."
