The baking goddess, 25, attended the film screening of Thomas And Friends: King Of The Railway in London (Sunday 18 Aug) and looked simply delicious in an orange knee-length skirt and bejewelled flipflops.
Her recently-dyed pink ombre hair was worn soft, complementing her natural-looking make-up and bronzed skin.
After spending Saturday toddler free at Virgin Media's V Festival, Luisa gave herself up to all things childlike as she spent Sunday with daughter Dixie, three.
Proud mum Luisa posted a pic of her daughter playing at the event, with the caption: "Dixie having a ball @thomasfriendsuk #thomas #premier."
She also tweeted her thanks for being invited to the starry premiere, saying: "Fabulous morning @ThomasFriendsUK 2 very excited very happy & very entertained 3 year olds!Thank you so much for having us."
Mistresses star Shelley Conn, EastEnders' Charlie Brooks and Celebrity MasterChef's John Thomson also attended the event with their children.
