Machine Gun Kelly allows daughter Casie

Machine Gun Kelly’s daughter, Casie, tattooed the singer while backstage at Hellfest Music Festival.

The “Forget Me Too” singer took the 13-year-old, who he shares with ex-Emma Cannon, along with him to France for the performance.

The twosome also made an appearance at Saturday’s Dolce & Gabbana event for Milan Fashion Week.

Kelly rocked liberty spikes while on stage at the music festival in Clisson, France.

It is unclear if Kelly’s on-again, off-again fiancée, Megan Fox, was in attendance.
