Kerry Katona will give Natasha Hamilton and Ritchie Neville the details of a divorce lawyer for their wedding gift.
The 36-year-old singer - who split from third husband George Kay last year - doesn't know if the couple will need the legal advice in the future, but if they do split, she'll be on hand to help her Atomic Kitten bandmate.
Asked what she'll get them as a wedding gift, she said: "The number of a good divorce lawyer. I'm not saying they will need it, but if the time comes, I'm an expert.
"I should become a lawyer myself, the amount of times I've been in and out of court."
Kerry - who has kids Molly, 14, Lilly-Sue, 12, Heidi, eight, Max, seven, and 22-month-old Dylan-Jorge from various relationships - insists she's currently happy being single but does miss having an adult conversation.
She said: "I'm happy on my own. I'm in love with myself at the minute. I'm still learning how to love me, how I should be loved and to respect myself."
Asked if she misses having a male companion, she told new! magazine: "It's not about a male, I miss a grown-up conversation. There's only so much you can talk to kids about. I FaceTime my mum a lot. She's down at the moment, helping out."
