That platinum pixie cut. Those long legs. That unforgettable stare.

If you remember the latter half of the 2000s, then you probably remember the name Agyness Deyn.

The 31-year-old, who walked in the biggest runway shows back in 2007, showed up to the London premiere of her new film, "Electricity," on Tuesday night [pictured below on the right] — and hardly looked like her former self.

Remember that iconic super-blonde hairstyle? Gone! Those gams for daze? Covered! That intense look? No more. All gone, gone, gone!

Back in 2012, the now long-haired, brunette beauty admitted she had retired from the modeling industry, saying, "I suppose I have stopped modelling officially. I've not done any for a good long while now. I think it was about four years ago when my feelings were changing towards the industry. I didn't hate it, but I was yearning to do something different. I was on a gradient. It was a gradual thing."

And acting is it!
