Sam Smith Weight Loss Update: Star Spotted Looking Hot In Miami [Photos]

Sam Smith's slimmer figure has been making headlines all year and now, the British singer has used social media to show off his skinny body and sun-burned top.

Currently, the 23-year-old superstar is on his "In The Lonely Hour" world tour and has continued to lose weight. His most recent jaw-dropping selfie was posted over the weekend when the "Stay With Me" singer flaunted his sunburn.

"My sun burn is SO BAD Lobster viiiiiiiibes Just had to make this top to give it some air hahhaaaaa Lord," wrote the star as he slowed off his tiny frame. The singer sported black shorts and a grey shirt that showed off his shoulders, which happened to be as red as a lobster!

According to Us Weekly, the Grammy winner has been serious about keeping a healthier lifestyle even while on tour. He recently revealed his fitness regime that allowed him to lose a pound a week, totalling 14 pounds in a matter of two weeks.

"I met a woman who has completely changed my life," wrote Smith on Instagram back in March. "Amelia Freer has helped me lose over a stone in 2 weeks and has completely transformed my relationship with food. 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 @ameliafreer #eatnourishglow."

He shared that his weight loss secret lies in the book of Amelia Freer, "Eat. Nourish. Glow."

It's very nice for me to see the results that I do get with my clients," quoted People of Freer. "By someone like Sam talking about how he's changed his diet in a healthy way without a deprivational, horrible diet, it's opened it up to thousands of people who are now following in his footsteps. Sam has a lot of young fans, and how cool that these young kids are starting to take care of what they are eating. To me, that's beyond awesome and a dream come true."

While the singer hasn't revealed exactly how much he weighs now or how much pounds he's lost in total, it's estimated that he has shed somewhere between 35 to 45 pounds already.

Sam has told fans before that it's not all about dieting, "It's not about weight loss, it's about feeling happy in yourself." He also pointed out that if one has time to be on social media, you definitely have time to be working out and exercising.
