"Pre show tourists….," the rocker captioned a set of pictures from the family's time exploring Budapest, a recent stop of Mötley Crüe's world tour alongside Def Leppard.

During this tour, the rocker has enjoyed sharing pictures of his backstage walks with Ruby. Not only did he share their walk together in Munich, but the father-daughter duo also sat together getting ready backstage, with Nikki sharing video where he shows his daughter how to apply makeup just like his stage makeup.

"Getting ready in Munich," he wrote.

Before the show, Nikki treated his little girl to some ice cream, sharing a photo of Ruby enjoying her ice cream while wearing a pink sequined bomber-style jacket.

"Pre show ice cream with Ruby before we lay down some rock for you German crazies," he wrote.
