The former Spice Girl attended the lavish nuptials of Kris' daughter Kim and Kris Humphries' last month, just days before she gave birth to daughter Madison, and although Mel was worried she could go into labour during the ceremony, Kris assured her she was very experienced at delivering babies.
Mel - who is married to Stephen Belafonte - said: "I went to Kim Kardashian's wedding a few days before I had Madison and it was amazing. Kim's mum came up to me and said she'd delivered Kim's sister Kourtney's baby, so I shouldn't worry if I went into labour. They also had a doctor on site who kept asking if I was OK."
Socialite Kim was also worried that Mel - who has two other daughters, Phoenix and Angel, from previous relationships - would give birth at the wedding and jokingly told her to wait until her big day was over.
Mel added to Britain's HELLO! magazine: "Kim actually came over and said, 'Don't you give birth today, Mel.' I think I would have stolen her thunder if I had."
