Celebs are using bleach like it's goin' outta style!

Kendall Jenner was the first to shock us with her newly-lightened locks on the Buberry runway on Monday. It's the first catwalk she's walked during this fashion season, at London Fashion Week. Fans have reacted positively, loving the new supermodel's new surprise look.

Meanwhile, teen heartthrob Noah Centineo's new blonde look isn't getting such a warm reception ... Centineo dyed his BEARD blonde - what?! The To All The Boys I've Loved Before star has a new color for his facial hair and fans want it CANCELLED NOW! One commented: "Noah centineo bleached his beard… you know you’re REALLY going through something when you bleach your BEARD." Another wrote, "For the very first time, i’m requesting that you please shave off your beard (i can’t believe i actually said that)."

Still, Noah-lovers are speculating the actor did the dying dead for his upcoming role as He-Man in Marvel Comics' Masters of the Universe. Centineo responded to haters in an Instagram Story video, tagging haircolorist Shah Karegar as he said, "I didn’t bleach my beard. That would be ridiculous." Uh, yeah it would!
