The mum-of-one announced her engagement to businessman Andrew Collins in October, but now it appears the pair of them may have already walked down the aisle.
Taking to her Instagram page this week, Luisa shared a picture of the back of a bride, walking down the aisle.
She also shared a separate snap of her enjoying a glass of champagne, meanwhile showing off a huge diamond sparkler.
Luisa is currently enjoying a break in Cannes, being joined there by friends Sam Faiers, Rylan Clarke and Casey Batchelor.
And interestingly, Cannes is exactly where the leaked wedding invites said the nuptials would take place - despite Luisa later claiming that the invites were ‘fake.’
Luisa added that she was ‘getting married in Ireland,’ and that she had deliberately sent fake invites in order to ‘flush people out.’
What do you think, is the mystery bride above our very own Luisa?
