He said: "Who'd have thought it!"
But he wasn't always a world-class hottie - Elba says he went through an awkward phase first.
Elba walks near a Mclaren sports auto while filming for the Fast and Furious movie franchise in Glasgow, Scotland, in October.

Elba, who recently directed the film "Yardie", also told the magazine that as a kid he "got picked on a little bit", but when he got older and grew a mustache he was the "coolest kid on the block". "Grew a mustache, had some muscles, bonkers", he revealed during the interview.
Elba will be featured in a special double issue that will hit newsstands later this week.
For now, the actor strives to live with as few regrets as possible. Thank you @people & all the fans for naming me #SexiestManAlive. 'I think everyone should adopt the philosophy that tomorrow is not promised so just go for it today, man.
