All the fun went down Wednesday on Philipps’ Instagram story, when the Freaks and Geeks actress lost her hairbrush and needed something fun to do with her friend as a distraction. “We’re gonna dye her hair pink. What do you think? Is this a good idea?” Philipps (herself already pink-haired) asked her fans on Instagram as Williams giggled nervously in the background. “Alright guys, here we are. I am going to dye Michelle Williams’ hair. Are you ready?” Looking for more style content?

But Williams started to get second thoughts the second her BFF began the coloring process. “You have to put it in for 20 minutes. I have it in my hand. It’s like pink slime. We will do it for like five minutes,” Philipps said. “Three minutes, two minutes, honestly like after one minute we should stop,” Williams replied. “Guys, I am putting the pink in. I am massaging the pink into the little pixie’s hair. Michelle’s hair is going to be perfectly millennial pink. She is going to wash it out in two minutes and it is going to be amazing,” Philipps said as she sipped on a glass of wine. After rinsing the hair dye out, Williams and her new master colorist debuted the fresh color while cuddling side-by-side in bed. And Philipps wanted to make sure we got the memo, shouting out PEOPLE directly to take notice of the new do. “Guys my best friend now has … I mean, she is kind of naked, and she has slightly pink hair and it is f–king beautiful,” Philipps said. “Michelle’s hair is slightly pink and so cute. And look, she is like a little nymph asleep next to me. Listen, PEOPLE mag!” (Message received, BP!) Busy Philipps/Instagram Philipps has been quite the proponent of pink hair lately. Earlier this year, the star turned to celeb-loved colorist Tracey Cunningham to update her blonde into a bright, highlighter-pink shade. “Is it the new me? Is this who I am now?” Phillips asked in a series of videos she uploaded to her Instagram story after the job was done.
