Anne Hathaway is a full brunette again.
The 33-year-old actress took to Instagram on Thursday to show off her new 'do, after rocking blonde highlights for the past couple of months.
"Getting back to my roots... #marierobinson," Hathaway captioned her selfie, giving a shout-out to her hairstylist.
Hathaway's been sporting blonde highlights since giving birth to her son, Jonathan, in April.
The Oscar-winning actress is no stranger to switching up her look -- like when she sported a pixie cut after her role in 2012's Les Miserables -- but her most recent brunette style is giving us some Princess Diaries vibes, and we're not mad about that!
ET spoke with Hathaway at the Toronto International Film Festival last month, where she dished about her first acting gig since giving birth -- the star-studded Ocean's Eight, aka the all-female Ocean's Eleven. Sandra Bullock, Cate Blanchett, Rihanna, Helena Bonham Carter and Mindy Kaling are all set to appear in it.
"Oh my God, I have so many questions," she told ET about working with her fellow A-list ladies. "They are fun and a lot of them are moms, so I am excited that my first film back as a mom, I get to work with women who have done it before and I get to ask them questions about that."
