Singer Mike Posner was airlifted to hospital after being bitten by a rattlesnake.

The pop star was attacked by the reptile during a hike he is currently doing across the US. 

After crossing from Kansas to Colorado on Wednesday, Mike shared a video showing him lying in a gurney while being wheeled along by paramedics.

The American singer, whose hits include Cooler Than Me and I Took A Pill In Ibiza, said he had been bitten by a baby rattlesnake and was taken to hospital by helicopter.

Posting on Instagram, he wrote: “That venom is no joke! I got to the hospital and got the anti-venom in time. 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!”

The 31-year-old 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, while 33% of bites do not contain venom.

Mike’s celebrity friends sent get well soon messages, with Joe Jonas wroting: “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.”

Mike 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.
