Heading into the capital to attend Macmillan Cancer and Ego Professional's charity event, Luisa couldn't stop smiling. Could it be the recent wedded bliss she is enjoying lately?
Earlier this month, Luisa sparked speculation she had finally wed her businessman fiancé Andrew Collins. While holidaying in the South of France, the Apprentice runner-up shared a photo of a bride - thought to be herself - with followers on Instagram.
In her snap, Luisa's face couldn't be seen, but the bride was pictured wearing a wedding dress and veil while clutching a bridal bouquet. Alongside the snap, Luisa had posted two emojis of a love heart and a bride, but quickly deleted her photo after posting it.
She later shared more photos of herself celebrating and drinking champagne with her friends including former TOWIE star Sam Faiers, Rylan Clark and her BFF Casey Batchelor.
Luisa joined Casey in London last night and the two friends looked like they had plenty of fun together.
While Casey looked gorgeous in her camel-hued dress, Luisa looked just as fab in a fitted red number and strappy black heels.
Luisa so far hasn't commented on whether she and Andrew have married, keeping us all still guessing. The starlet announced her engagement in October last year, telling fans she "felt like the luckiest girl in the world" after her beau popped the question.
She and Andrew had been enjoying a romantic trip in Paris at the time, with Luisa sharing a photo of her HUGE engagement ring while they were away.
This will be Luisa's second marriage. She previously wed Oliver Zissman, the father of her daughter Dixie.
