A photo of MÖTLEY CRÜE bassist Nikki Sixx's newest tattoo — a portrait of CRÜE guitarist Mick Mars — can be viewed below. Kat Von D, the "L.A. Ink" star who is dating the bassist, did the artwork.Footage of Sixx getting the tattoo will be aired on the October 23 episode of "L.A. Ink". The show airs Thursdays at 10 p.m. on The Learning Channel (TLC). Commented Kat: "At first, when Nikki brought the idea of getting this tattoo done, I thought how cool it would be to celebrate a friendship between two people over three decades! "We decided it would be so rad to do the tattoo without telling Mick, so on the show, you'll be able to see the tattoo process, as well as the entire High Voltage crew rockin it out at Crüe Fest in Los Angeles, which to me, was by far one of the greatest shows from the tour — amazing energy!" Sixx wrote on his blog on Sunday (October 19): "Katherine tattooed a killer portrait of Mick Mars on my leg and we got to surprise him with it at the Los Angeles Crüe Fest show. It was a pretty emotional rollercoaster ride to share the whole experience with Katherine, from the beginning of the idea to the end when we finally show Mick." Sixx said he had a "fucking blast" getting the tattoo.
