Writing in her OK magazine column, the twice-divorced reality TV star expressed shock at a number of celebrity couples who split up over the Christmas period.
Commenting on the split between Katy Perry and her husband of 14 months, Katona said of the comedian: "He once said he'd 'give me one'. He's proper hot-blooded stuff, but it's sad when any marriage ends."
Katona also wrote about the split between Sugababe Heidi Range and DJ Dave Berry, admitting that she was "most surprised" to see their relationship end.
"Theirs was such a long relationship, but hopefully Dancing on Ice will help Heidi get over it," she said. "That show happened at the perfect time for me - I'd just left my husband and it really helped me move on."
Meanwhile, Katona also dismissed reports that she is engaged to, and living with, boyfriend Steve Alce.
"It's the first I've heard about it," she said. "Although the more time we spend together, the more I think that marriage could be a reality. He's wonderful!"
