Luisa Zissman isn't having much luck with her dresses of late - first she nearly fell out of her frock at the Pride Of Britain Awards earlier this week, and now she's suffered the (ahem) dreaded flashbulb flash wardrobe malfunction.
The former 'Apprentice' star revealed slightly more than she (probably) intended as she attended a screening of 'Jackass Presents: Bad Grandpa'on Wednesday night.
The flashbulbs of the awaiting paps managed to reveal that she definitely wasn't wearing a bra, exposing her boobs through her transparent blue frock.
However, she was later seen leaving the event covering her chest.
Perhaps she'd remembered our formula - sheer dress + no bra x pap flashbulbs = flashbulb flash.
