Two weeks ago, Diana transformed her blonde, mermaid locks into a flaming red do... and now it's turned peach!
Diana had her locks dyed pillar-box red two weeks ago at Bleach London and while it received mixed reviews from her Instagram followers, we loved it for a dramatic, eye-catching change.
But now it's started to fade out, it looks even better!
"Me hurrs dead peach now," the 'Cinderella' singer posted on Thursday (4 September).
Peach hair might not be top of everyone's must-have colour for 2014, but we think it looks rather fabulous on the former X Factor contestant.
Although she could probably go sludge yellow and still look ridiculously pretty!
The Hills' Lauren Conrad has also went down the peachy hair road when she dyed her blonde tips a warm, apricot colour back in October 2011.
And Sienna Miller has also worked a similar, pinky-peach hue in her time, most notably at the end of last year when she rocked up at the British Fashion Awards at the London Coliseum with a warm tone to her blonde locks.
Celebrities 'doing peach', however, are few and far between and we don't really know why...
Hopefully Diana's cool, faded do might get some of them contemplating a peachy hair change for the new year.
After all, it's a pretty cool colour, don'tcha think?
