Smith has always been outspoken about the struggles of his weight loss journey, even admitting that hearing someone call him "fat" hurt more than anti-gay slurs.

"If someone called me fat, that affects me way more than someone calling me a f----t," he admitted to Australia's 60 Minutes last April. "I think just because I've accepted that, if someone calls me a f----t, it's like, I am gay and I'm proud to be gay so there's no issues there. If someone calls you fat, that's something I want to change."

The big-voiced Brit also admitted that he was looking forward to Lady Gaga's tribute to David Bowie. "I was just enamored constantly by him, and his work, and his constantly changing and how fresh he was," Smith said of the late icon. "It's going to be emotional tonight to see that."
