Asked about the delay in her daughter's wedding, she told TMZ: "She's promoting her fragrance right now and her new skin care and literally she does not have the time right now.
"They're very nice, we were with them just recently and they seem to really enjoy each other's company."
Asked if either of them had cold feet, she said: "I don't think so, I really don't think so.
"[Was it a pre-nup issue] No."
Paris was initially keen to have a "winter princess" wedding because she wanted it to reflect Chris' proposal on the ski slopes of Aspen, Colorado, back in January.
A source previously said: "Paris loves a party and wants this one to be the most memorable yet. She is planning to have icicles everywhere. It will be a real winter wonderland."
She said: "We've been getting a lot of calls and a lot of offers from different networks, pitching that show so maybe."
