Don't freak out yet, though. It seems like the "tattoo" may not be a permanent one. Delevingne's long-time hairstylist, Mara Roszack, posted a photo of Delevingne's new design to Instagram.
"I am in awe of this incredible creature," Roszak wrote in the caption. "The beautiful #CaraDelevingne with a little head design drawn by me."
The design may only be temporary, but lately, so are Cara Delevingne's hairstyles. WHAT WILL SHE DO NEXT?
