Kim Kardashian, 35, has sensationally revealed she snapped up to 6,000 selfies while vacationing in Mexico for just four days in August.
Mrs West explained how she managed such a feat on her sister Kendall Jenner's app on Wednesday.
Kim stayed in her pal Joe Francis' Punta Mita mansion with her daughter, North, 3, and son, Saint, 9 months, and shot several types of selfies.
During the takeover of her sister's app she also revealed that her and daughter North drank 10 watermelon smoothies in Punta Mita, and that she spent several hours on the beach with baby Saint.
