Holly Willoughby has channeled her inner Julia Roberts this week as she wowed fans with a Pretty Woman-style dress.

The This Morning presenter turned her flawless style up a notch on Tuesday in a stunning polka-dot frock complete with an elegant bow at the waist and a ruffled hem skirt.

And if you’ve ever watched Pretty Woman – Holly’s ensemble is remarkably similar to Vivian’s dress when she heads to the polo with Richard Gere’s character Edward.

But while the mum-of-three’s followers loved the look, it seems as though Holly has taken some unlikely inspiration from old pal Keith Lemon.

Holly’s Celebrity Juice co-star and long-time BFF is known for his incredible fancy dress, and while filming for Keith and Paddy’s Picture Show earlier this year he also transformed into Julia Roberts.

Wearing the same spotty dress – but with Keith adding a white hat and chunky brown belt – the co-stars are basically twins… kind of!

Quick to share the hilarious matching outfits on Instagram, Holly posted a photo of the pair side-by-side along with the caption: “Not again”.

Not again… @keithlemon 😩

Obviously, Holly’s fans were quick to comment on the snap, with most asking the important question: “Who wore it best?”

One follower joked: “Which one are you?”, while another said: “The resemblance is uncanny 👌”.

A third joked: “This is the worst example of ‘who wore it better’ in the history of fashion,” and a forth added: “I can’t tell them apart 😂😂😂”.

Last month Keith also showed a load more photos from his Pretty Woman re-make, including this hilarious snap of the iconic Piano scene.

Meanwhile, this isn’t the first time Holly has taken inspo from Keith and back in January the 37-year-old wore a strikingly similar outfit to present Dancing On Ice.

Sharing one of Holly’s snaps with a throwback photo of himself wearing a white suit with the same feathered shoulders, he joked: “Always been @hollywilloughby‘s style inspiration.”

We’re sure this isn’t the last time Keith and Holly will turn up in the same outfit!
