The "Stay With Me" crooner showed off what looks like a ridiculously painful sunburn on his Instagram page Monday, after spending a little too much time exposed to the Miami sun.
But it's his impressive weight loss that's creating some serious buzz.
"My sun burn is SO BAD Lobster viiiiiiiibes Just had to make this top to give it some air hahhaaaaa Lord," he captioned the shot, which puts his damaged skin front and center.
It's clear that the singer has been hitting the gym, but he recently admitted that a drastic change in his diet also made a huge difference.
"Amelia Freer has completely transformed my relationship with food," the 23-year-old star shared earlier this year, giving props to his nutritionist. "Everyone go check out her incredible book, and start to live healthy. It's not even about weight loss it's about feeling happy in yourself. Love you Amelia & thank you for making me feel so happy inside and out."
"For me the key is about it being real," Feer said in an interview with "GMA." "Getting back in the kitchen, cooking from scratch, making sure they are not relying on junk processed convenience food."
Lookin' good, Sam -- just don't forget the sunscreen next time!
