"#nofilter #sparks @adambreuchaud @etienneortega @hannahluxdavis @brettalannelson @amylilfire," she captioned the shot.
In the photo, the "Younger" star snaps a selfie from the set of her music video for her new single "Sparks" as she flaunts freshly dyed gray roots which fade into pink ombre tips.
The actress continued the pink theme with a bold fuchsia lip and a hot pink embellished jacket. The newly single star definitely wants to make a statement -- and we're loving her bold look!
No word on what inspired her latest look but Hilary did open up about what prompted her initial hair change.
"I've never done anything like this! I was just in Cabo with my son and I was staring at the ocean, and I was like, I want that on my head," she explained on "The Ellen DeGenres" show. "So this happened."
