Lifestyle Style Justin Bieber, Rachel Bilson and More Are Having Blonde Moments Rachel Bilson's subtle change is so pretty. By Jillian Ruffo Published on December 2, 2015 10:49 PM Share Tweet Pin Email Things are looking particularly golden in Hollywood this week — when it comes to celebrity hair, anyway. So whether you’re going for a subtle pick-me-up like Rachel Bilson or a bold change like Zosia Mamet, a star has the blonde-spiration for you. Courtesy Justin Bieber Justin Bieber posted a shot of his almost-platinum hair pulled in front of his face on Instagram Tuesday, writing “Haircut need.” Now that’s something we can get behind — his bleached strands are approaching lenghts not seen on him since the original Bieber cut — and now that he’s pulled off Brad Pitt-inspired “swoop”, we’re ready for a full Matt Damon-esque head shave.

Our 2015 Hair and Makeup Superlatives Speaking of cuts, Zosia Mamet’s Girls character, Shoshana, is sporting a full-blown platinum chin-length bob — with bangs — in the Season 5 Girls trailer. While we saw a similar look on Mamet back in April, it’s bolder and brighter in the clip. The Girls actress is no stranger to a major mane makeover; she’s flaunted platinum and even gray hair in the past.

The just-this-side-of-edgy do had us snapping pics of the Today Show set while she was discussing her film Spotlight. And lest we forget there are many ways to be blonde, Rachel Bilson revealed subtle blonde highlights by color master Tracey Cunningham on Tuesday. The new mom tells PeopleStyle, “Considering I haven’t had my hair colored in over two years, I didn’t want to do anything too crazy.” She adds, “It looks like the beach could have done it, maybe.” Are you taking blonde-spiration from the stars?
