He shared an image on Instagram with the caption: "Who'd have thought it!" I got picked on a little bit, ' he continued to the publication. "But what's even more important is your vote in the midterm elections".

Elba has a 16-year-old daughter, Isan, and a 4-year-old son, Winston, from previous relationships as he cites being able to witness their births as 'the biggest and best thing ever'.
He has two children, and proposed to his model fiancee Sabrina Dhowre, 29, in February. "Grew a mustache, had some muscles, bonkers", he revealed during the interview. And nab your own official Sexiest Man Alive shirt from our brand new Amazon store!
