Simon Cowell introduced her replacement on the TV talent show yesterday to a bevvy screaming fans and wannabes. And the outfit for her first official engagement? The former Pussycat Doll kept it - unsurprisingly - short and sweet in a thigh-skimming silver foil minidress and towering platform Louboutins.
It's not exactly our cup of tea, but we're still thankful that she has learnt from Cheryl's mistakes and steered well clear of eye-zapping colours and bouffant hair.
