The Coming Clean star will appear in the four-part Channel 5 series Celebrity Wedding Planner from January 6, The Sun reports.
Katona will be set the challenge of organising an entire event for happy couples, with everything from the cake to the venue decided by her.
The Celebrity Big Brother star was married to ex-Westlife singer Brian McFadden from 2002 to 2004, and split with second husband Mark Croft after a three-year union in February 2010.
She claimed last month that she had fallen in love again with artist Steve Alce, who she met at a charity event in October.
"He is lovely... kind and caring," she said at the time. "Steve is so unlike other men I have been with and I can honestly say I have never felt this strongly about anyone before."
