Most know her as Alex Dunphy from hit comedy TV series Modern Family.
But now Ariel Winters is all grown up – and looks completely different from the geeky teen character we know and love.
The 21-year-old took to Instagram over the weekend to share a transformation shot, looking almost unrecognisable with a new ‘do.
Since landing a role on the hit show aged 10, she has always worn her hair in long, black layers.
In the snap posted, fans were surprised to see that her hair was a light shade of ginger, falling around her face in surfer waves.
As the photo was taken in her hair salon in Los Angeles, California, it seemed to have been a fresh haircut.
On top, she wore a racy black top with a deep plunge neckline.
A pair of simple blue denim jeans completed the outfit, showing off her slim and toned physique.
With a dark nude pout and a smattering of freckles across her cheeks, she looked sensational.
Racking up over 494,000 likes, her fans couldn’t get over the change, with many likening her to flame-haired actress Bella Thorne.
One fan said: “I’m super confused. Is that you?”
A second chipped in: “I thought this was Bella Thorne!”
And a third gushed: “Bella Thorne who?”
Bella herself even added to the comment section, simply writing, “Love”.

She then continued: “I want to gain a few pounds of muscle and get healthier. Also, want my butt back…”
