Jon Gosselin is NOT happy with his twins' unflattering portrayal of him!
The uber talented singer sported a slightly more punky look than were used to seeing at the 2014 BRIT Awards!
However, he was back to his old amazing antics when he took the stage for a performance of Treasure!!
Seriously, if James Brown and Sid Vicious had a baby, it would look something like this performance!
Ch-ch-check it out (above)!
