During Kim's interview with Ellen, she revealed when North first met Caitlyn Jenner.
"I brought North over for Mother's Day … no, it was Father's Day," the 34-year-old reality star recalled. "And I called and I said, 'You’re really inviting us over for Father's Day? Are you expecting a gift? You're not double dipping here. Are you Mother's Day or Father's Day?' Like, you get one gift."
