American pop star Mike Posner has been airlifted to hospital after being bitten by a rattlesnake during a cross-country hike.
The singer shared a video from hospital, showing him lying in a gurney while being wheeled along by paramedics.
He has been walking across the United States and crossed from Kansas to Colorado on Wednesday, according to his Instagram page.
Posner, whose hits include Cooler Than Me and I Took A Pill In Ibiza, said he had been bitten by a baby rattlesnake on his journey.
The star said he was taken to hospital by helicopter and “got the anti-venom in time”.
"That venom is no joke!” he wrote in a post on Instagram.
“Shout outs to G and Mike from the chopper team and Bo and Cassie and Whitney (my nurses).”
"I'll be here a few days and will not be able to walk for several weeks but enjoying the AC and the nice bed, haven't had those in a while Hahahaha!"
Detroit-born Posner, 31, added: "Can't wait to get back on The Walk! KEEP GOING!!!!!!"
Rattlesnakes bites on people are rarely fatal, with less than 1 in 600 resulting in death, according to the US Forest Service.
Some 33 per cent of bites do not contain venom.
Posner's celebrity friends sent get well soon messages in the comments section.
Joe Jonas wrote: "Rest up bro. Glad you are OK."
Millie Bobby Brown said: "What!!! Get well soon, sending best wishes to you."
And Jessie J commented: "You are a real life super hero."
Ponser embarked on a hike across the US in April, starting in Asbury Park, New Jersey.
He plans to walk 20 miles a day, reaching California in September.
