On seeing her walking down the steps of her London hotel yesterday, on the way to her latest premiere, you could be forgiven for feeling a sense of déjà vu. The girl, the dress, the princess aura. Lily James, trailed by long term actor beau Matt Smith, sauntered towards photographers in a dreamy Oscar de la Renta gown complete with ballooned hem, full skirt and fitted bodice. The total Cinderella package.

And despite being on route to the premiere of her new film Mamma Mia 2: Here We Go Again! where she plays the younger version of Meryl Streep’s character Donna, she gave us definite throwbacks to the time she played the title role in Kenneth Branagh’s 2015 version of Cinderella.

Mamma Mia 2: Here We Go Again! begins in cinemas around Australia tomorrow and it’s James’ all singing, all dancing performance that’s being touted as the one to watch. The breakout star despite the film receiving mixed reviews. Even Meryl Streep has given her the seal of approval, exclaiming “I had no idea Lily James had these singing chops!”

So just who is this beautiful triple threat? Lily James is an acclaimed British actor best know for her aforementioned roles as well as her parts in TV series Downton Abbey and last year’s hit indie film Baby Driver. At 29 she has already drummed up quite the portfolio, however it’s the ABBA-loving prequel which is set to launch her into worldwide superstardom. Her boyfriend, and rumoured fiancé, Smith is known for his role in the BBC’s Doctor Who and also starring in cult series The Crown.

Already darlings of the London circuit, they are sure to become a power couple the rest of the world will be watching. And with the chic style James has been bringing on the promotional trail for Mamma Mia 2, it’s likely the fashion set will be taking notes too.
