Bye-Bye, blonde! Maggie Gyllenhaal is back to being a brunette. The 36-year-old actress stepped out in New York City on May 29, revealing she's gone back to her roots.

Gyllenhaal surprised fans when she first changed up her look back in April at the Cannes Film Festival, where she debuted new, bright blonde tresses at a photocall for her film The Honourable Woman.

The mom of two took to her Twitter to share she'd gone lighter, writing simply: "In Cannes with The Honourable Woman. I'm blonde btw."

Whether the longtime brunette just got over being blonde or is preparing for an upcoming movie role is unclear.

What is clear is that the actress enjoys her short 'do, considering she's been rocking the pixie cut over a year now.
