The reality TV star - who admits to cheating on his wife during a one-night stand in Toronto last year - revealed his new inking on the reunion episode of 'True Tori' last night (03.06.14), and stated that it represents his promise to never be unfaithful again.

Speaking on an episode of 'True Tori', she said: ''Should I have him do a tattoo on his body? I mean clearly that didn't stop him. You know the tattoo he has, right? Down there it says Tori's.
''It's above [his penis]. It's above the pubis. It says, 'Tori's'. And then months later he cheated on me.''
