Olly Murs knew he had some competition in the hunk stakes at the Capital Summertime Ball, what with Justin Timberlake hosting and all, so the former 'Xtra Factor' host decided to bring Sexy Back himself by flashing the crowds.
Olly treated fans to a cheeky glimpse of his naked torso (and impressive chest rug) by lifting up his shirt while on stage at Wembley Stadium on Sunday.
However, the singer reckoned it wasn't so intentional on Twitter after the show.
When a fan tweeted the picture at him, he said: "Ha ha I'm having a fight with my shirt."
During his set, Olly was also joined by Rizzle Kicks for his number one hit 'Heart Skips A Beat'.
And after he came off stage, he was finally introduced Justin Timberlake, and managed to grab a picture with his hero.
"Can't tell you how much I wanted this picture..saw this GUY back in '03 JUSTIFIED Tour..10yrs on..i've met him," he tweeted.
