While on the show, he also said that he got all of his tattoos to prove that he was 'tougher' than Justin Bieber. 

I was always so scared to get one and then I got one.

"We were working on [debut album] 'Stoney', and then we had a tattoo artist came through, and I was like, you know what? Justin Bieber's got some tatts, and I love you, but I know I'm way tougher than you."

By the looks of it though, Post has obviously gotten over his fear!!
