Louise looked chic in a pale blue and white checked coat, and showed off her legs in strappy snakeskin print heels.
The brunette was all smiles as she joined Alik for a photo on the blue carpet, and it looks like New Yorker Alik found something particularly funny judging by the huge grin on his face!
After watching the film, Louise told fans on Twitter: "Cate Blanchett's outfits were EVERYTHING in the @CinderellaMovie... mega style envy!"
Louise and Alik were joined by co-star Spencer Matthews and his girlfriend Lauren Frazer Hutton, who showed off their golden tans following their recent holiday to Morocco.
Louise and Alik are still filming for the show's brand new ninth series, which is making a return to our screens next month!
Joining the Chelsea favourites will be five new cast members - Emily Weller, Jess Woodley, Fleur Irving, Millie Wilkinson and Josh Patterson (also known as JP) - and the addition of Alex Mytton's girlfriend Nicola Hughes.
