The 27-year-old star, who won the fourth series of the singing competition with Danni Minogue as a mentor, has posted snaps of himself on Instagram for the first time in the best part of a year, revealing a small insight into his life in the USA.

The Scottish-born singer shared several selfies of himself in the car, as well as picking pumpkins with his 12.8 thousand followers, revealing that he has come a long way from his suit and skinny tie days as he posed in a jacket and hoody, showing off his thick stubble and styled brunette hair.
The 27-year-old caused a stir back in January after sharing photos showing off his toned physique. However, he has since stayed out of the spotlight, with his last post on his official website wishing fans a Happy New Year back in 2012. Despite this, it is clear that his Instagram followers are pleased he has made a return to social media, with one commenting: "Nice one! Glad to see you're doing well :) miss you x."

Another added: "Looking good bro."
Speaking about leaving the music industry back in 2010, Leon wrote on his website: "I've needed time to consolidate and make sense of everything I've experienced. I needed to fall in love with music again, this process has been slow and wrenching at times but I'm now feeling liberated and fulfilled for the first time with my work.
Leon was known for wearing suits with skinny ties
"Music is a conversation between the singer and the listener, and to that end the fans are the foundation of everything I do."
