Leighton, 26, showed off her new, shoulder-length hair at a party in Hollywood yesterday (25 October) and told reporters she'd gone for the chop right after filming ended.
She told US website Just Jared: "My long, wavy hair got a lot of mileage, so it was time for a change."
And hair isn't the only big change that Leighton is apparently making - it's been claimed that the actress is planning to relocate to sunny Los Angeles now that the New York-based Gossip Girl has ended.
She recently told US magazine Vulture that she felt Gossip Girl was ending at the right time: "I was 20 when I started, and I'm 26 now, so you don't want to be doing the same thing over a period that long.
"This has been one of the most awkward and great growth periods of my life. I've experienced a lot of different things, and it's just time to do something else."
