Ashley Roberts, 41, suffered a wardrobe malfunction as she exposed her bare breast while posing with Heart FM co-star Amanda Holden, 52.
The Pussycat Doll wore a skimpy two-piece consisting of a beige crop top and tiny mini skirt.
However, when Ashley lifted her arm up to pose with Amanda, her top had ridden up and she flashed her boob.
She didn't seem too bothered though as still uploaded the snap to Instagram but with a sun emoji to cover her modesty.
Amanda also looked stunning in a strapless black jumpsuit with a lace bodice.
