British pop star Rita Ora has signed on as the new face of luxury Italian fashion house Roberto Cavalli. The R.I.P. hitmaker, who has previously fronted ad campaigns for DKNY and Madonna's Material Girl line, has been teasing fans about an upcoming "surprise" with her recent Instagram.com snaps, including one photo of herself with the top designer's wife and business partner, Eva Cavalli, in New York. Soul singer Maxwell, who took the pictures on Saturday (26Apr14), confirmed the news by uploading his own image of Ora and Eva Cavalli, alongside the message, "congratulations @eva_cavalli and (photographer) @francescocarrozzini for the amazing @ritaora cavalli f/w (fall/winter) campaign #cavallifriends". The group later celebrated the new collaboration with dinner at Omar's restaurant in Manhattan's West Village, where they were joined by rap mogul Russell Simmons. The Cavalli deal comes shortly after Ora wore a sheer black dress from the label for a recent performance at the Coachella music festival in California. It is the singer's latest venture into the fashion world - she is also due to launch her first range with sports brand Adidas Originals, and recently unveiled her capsule collection for British cosmetics firm Rimmel.
