The former X Factor contestant showed off her flaming new locks on Instagram on Sunday (24 August) along with just two words: "RED HURR"!
Diana's known for her angel blonde tresses, but clearly wanted to up the ante and change her image when she opted for this drastic new hair colour.
There were mixed reviews from her Instagram followers, but we reckon one particular fan hit the nail on the head with her well worded comment about the 'Music to Make the Boys Cry' singer's new look...
"You rock what you want. I'm sure us sours will get used to it. It's what you like that counts!"
We couldn't have put it better ourselves and actually, we've totally got used to it already.
Diana's red hair colour is probably just a temporary measure and we bet she'll be blonde again before we can say 'pass the hair dye'.
But with Kelly Osbourne sticking with her lavender locks, Nicole Richie still looking fabulous with her electric blue barnet and no end of celebrities trying out pastel dip-dye and rainbow streaks, it seems that vivid hair colours are definitely here to stay.
All of a sudden our barnets are looking very boring indeedy...
