Mackenzie Ziegler is sporting some VERY unique new ink! We have to say, we've seen a lot of wild tattoos, but Kenzie has shocked us completely! On Instagram Wednesday, Maddie Ziegler's little sister posted a new video in preparation for her upcoming single called Tan Lines... and that's exactly what the tattoos were. Throughout the video, the 21-year-old can be seen sitting in a tattoo studio while the artist puts tape on her shoulders to match her bikini top.
