Singer-turned-actor Jon Bon Jovi is currently in Rome for the final days of filming the drama "U-571" with Matthew McConaughey, but he already has at least two benefit appearances planned for when shooting wraps.The first is a live performance on June 9 in London at a fashion event for Donatella Versace. Tagged "Diamonds Are Forever: The Millennium Celebration," the affair supports of a number of causes, including the Prince of Wales Foundation for Architecture and several cancer charities. Prince Charles is expected to be in attendance, along with a long list of other celebrities. The dress code is described as "black tie and diamonds." The singer's second appearance will take place during a somewhat less formal function in (literally) his own back yard. Jon and his wife Dorothea, along with football star Doug Flutie and his wife Laurie, are hosting a fundraiser for children with autism at their new home in Red Bank, New Jersey in mid-June. The festivities will include a cocktail reception, dinner, live music, and a charity auction. The entire Bon Jovi lineup is expected to attend the invitation-only event, along with a cross section of entertainment and sports professionals. Fans lacking invites will have to settle for seeing the frontman on the silver screen in mid-July when his film "Row Your Boat" makes its debut at the Stony Brook Film Festival on Long Island, New York, on July 21.
