Miley Cyrus hasn't yet spoken about whether or not her new hairstyle is a nod to the late Princess, but it wouldn't be a huge surprise. Latest album "Plastic Hearts" has a real retro glam-rock vibe that's a throwback to the second half of the 20th century, and takes influence — or in some cases guest vocals — from female rock icons of the time like Joan Jett, Debbie Harry and Stevie Nicks (via The New Hampshire). 

Given that Princess Diana is now seen as vintage style icon in the same vein by many, and has experienced a resurgence in popularity among younger people (via Grazia), it's not too outlandish to suggest that Miley could have been paying tribute in her own way. Could this prove the start of the mullet-mushroom — as seen on Diana above — making a comeback? We wouldn't bet against it, but it's always hard to know what Miley Cyrus will do next.
