Testino, Donatella, Diddy and Mariah are at Rio's Oi Fashion Rocks

Tonight the Brazilian fashion world is sizzling with zillions of feverish tweets fired off commenting on the Oi Fashion Rocks fashion event in Rio. Oi, a phone company, is the sponsor of the extravaganza held at Rio's Copacabana Palace hotel and Jockey Club. Calvin Klein, Marc Jacobs, Givenchy, Versace, André Lima, Lenny, Alexandre Herchcovitch and Lino Villaventura will have runway shows, while the event will also feature pocket shows by Mariah Carey, Grace Jones, Diddy Combs, Daniela Mercury, Wanessa & Ja Rule, Ciara, Estelle e Stop Play Moon.

For those who speak Portuguese, the live "coverage" is available on Twitter, just follow the #oifashionrocks hash tag (but be warned: it's more like senseless gossip and nasty remarks sprinkled here and there with nuggets of actual useful info).
