Julia Roberts is the prettiest woman in town as she pulls on a thigh-skimming minidress and dazzling silver heels for the UK launch of new movie Leave The World Behind

Julia Roberts was every bit the Pretty Woman on Wednesday night as she celebrated the UK launch of new film Leave The World Behind in London.

On a freezing night in London, the Oscar-winning actress, 56, warmed up for proceedings in a thigh-skimming miniskirt and dazzling silver-embellished heels as she greeted fans outside Curzon Mayfair.

A powder pink double-breasted blazer completed the look, while a diamond-encrusted necklace complimented her statement shoes as she walked into the venue.

Roberts was joined by co-star Myha’la Herrol and director Sam Esmail at Curzon Mayfair ahead of the psychological thriller’s official UK release on December 8.

But the actress, who is also co-producing her latest film, was without co-stars Kevin Bacon, Ethan Hawke and Mahershala Ali.

The actress celebrated the launch of her new film after sharing a rare photo of herself with her twins Hazel and Phinneas.

To mark their 19th birthday next Tuesday, she uploaded a black and white throwback to her childhood with her little bundles of joy.

Both twins were safe in their mother’s arms as they sat on her lap.

“There are no words for the joy, fun and wild rush of life together,” the proud mother wrote heartwarmingly in her caption.

The Pretty Woman star, 56, shares her twins and 16-year-old Henry with her second husband, cinematographer Daniel Moder.

Julia and Daniel celebrated their 20th wedding anniversary on July 4 last year, after tying the knot at her ranch in New Mexico on Independence Day 2002.

In an interview a few months after their milestone anniversary, Julia gave a hint as to why their marriage has proven to be such a keeper.

“I always say the same thing and I stand by it,” the Hollywood superstar explained to E! News. “It’s making out. Lots of making out.’

She gave the interview alongside her Ticket To Paradise co-star George Clooney, who joked: ‘I make out with Danny too.’

During the same promotional tour, Julia and George appeared on the Today show, where she gave her reflections on motherhood.

Julia explained her theory that children “have chosen us in this moment to be their stewards and their shepherds in this life experience.”

She met her husband “when I was ready,” and “you call these children into your lives when we are ready to be the best partner with them.”

The Eat Pray Love star confessed, “Sometimes I get gripped by the fear of screwing up, and sometimes I just say to my kids, ‘So today, as a mother, can we just take that off? the planks? Because I screwed up.”
