The 'She Bangs' hitmaker, along with his back-up singers, dancers and band, will be dressed by the designer in a number of custom-made Emporio Armani outfits.
Giorgio has created black leather jackets for a punk-themed opening set and Ricky will wear a number of other items in the Mediterranean and African sections of the show.
Giorgio confirmed he was excited to be doing the collection because of the level of "talent" the star has.
He told WWD: "Ricky personifies today's modern man is an extraordinary talent. Last summer, Ricky attended my Emporio Armani men's fashion show in Milan. We became enthusiastic over the prospect of collaborating again."
Giorgio has previously worked on tour outfits for eccentric pop star Lady GaGa, something he claimed he was "delighted" about.
He said: "Her energy, eccentricity and her extraordinary interpretative talent come over at their very best in a live context. I am absolutely delighted to have contributed both clothes and accessories to these appearances."
