They have been enjoying an Icelandic adventure but Kim and Kourtney Kardashian had a scare when their helicopter was forced to make an emergency landing on the Nordic island.
The reality TV stars, who are used to living their lives on camera, shared a series of photos on Instagram during their trip and documented the drama by posting videos on Kim's Snapchat.
In one video, Kim turned the camera on herself and mouthed the words: "Emergency landing", before Kourtney urged her sister to "stay calm".
In another Snapchat video, which showed the helicopter on the ground and the pilot outside the cockpit, Kim explained: "We found the problem! A seatbelt was hanging out that was making a rattling noise."
The Kardashian sisters have been joined on the trip by Kim's husband Kayne West, singer The Dream and family friend Jonathan Cheban, who appeared on Celebrity Big Brother.
Kourtney celebrated her 37th birthday on Monday.
