While Kathy didn't reveal the "something old" details, she did spill on some of Paris' wedding cocktails. "We're doing a special drink, Moët Rosé Impérial Champagne. And I wanted to have a little pink," she said. "Paris has to have a little pink in her wedding."

The cocktails will include pink cotton candy and "secret touches" to add extra fizz, Kathy said. She also added that she designed the champagne glasses that will hold the signature drinks.

Honoring tradition, the mother of four also confirmed Paris will stay with her family the night before the wedding. "She must spend the night here with us the night before. That's a tradition," Kathy said.

The star's entire wedding-planning journey will become public on Thursday as well, in Peacock original series Paris in Love. A trailer for the series shows the Cooking with Paris host trying on dresses, looking for venues and coping with the pre-marital stress of planning a perfect wedding.
