After she dyed her hair a "mermaid" blue-green in March and then greenish-blonde earlier this month, the 27-year-old actress switched up her 'do again, showing off her bright pink ombre hair on Instagram Monday.
"#nofilter #sparks @adambreuchaud @etienneortega @hannahluxdavis @brettalannelson @amylilfire," she captioned the shot, giving credit to hairstylist Etienne Ortega for the new look.
While Hilary hasn't revealed why she dyed her hair pink just yet, she previously explained why she made her first drastic hair color change last month during an appearance on the The Ellen DeGeneres Show.
"I've never done anything like this, and 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 told Ellen DeGeneres. "So this happened."
The "Sparks" crooner also dished on whether her 3-year-old son Luca has been loving all of the changes, adding, "Here's the thing: Luca is very particular about how he likes my hair. There are absolutely no buns on my head, no ponytails. I'll have a ponytail and he's like, 'Um, hair down, Mom. Hair down, please."
"Now he likes to go through his roster of colors that he knows," she continued. "He's like, 'Your hair's purple,' and I'm like, 'No, it's green.' He's like, 'Nah.' I'm like, 'Yeah.' He's like, 'It's blue.' 'No.' 'It's purple.' 'No.'"
Until we get word on whether Luca is into Hilary's pink look, we want to know...are you loving it? Tell us in the comments!
