Kirk has been busy hitting the casinos and bars in Las Vegas, but before he returns home, he wanted to get a lasting reminder of his trip.
Along with his pal, the reality star headed to a Stateside tattoo parlour and got an inking of a skull and crossbones on his hand. His fetish model friend, Cami Li, also got the same design scrawled on her wrist.
Sharing a photograph of his new body art on Twitter, Kirk said: "What happens in #vegas stays in #vegas apart from this!!! #TeamTatt."
This is by no means Kirk's first tattoo. The star already has a giant microphone and rose tattoo on his shoulder, along with inkings on his stomach and back.
