The members of One Direction are worried for the safety of the fans who have been camping outside their hotel in Adelaide, Australia.
According to the Australian Associated Press, a "small gathering" of fans has been staking out the Novotel Barossa Valley Resort, where the band is staying, since they flew into the country on Sunday.
In the hopes of catching a glimpse of their idols, fans have been ignoring signs outside the hotel warning of poisonous snakes and invading the "snake habitats" around the resort's perimeter.
When the band members learned of this, an alarmed Liam Payne sent a series of tweets urging fans to be cautious.
