Nelly Furtado has notched up a third week at the top of the US singles chart with her catchy summer anthem PROMISCUOUS. The Canadian pop star's collaboration with hip-hop producer Timbaland kept Gnarls Barkley's CRAZY off the top of the new Billboard list. The club anthem climbs to number two. R+B newcomer Cassie's Me + U also climbs, from four to three. The Hot 100's top debut is Justin Timberlake's SEXYBACK, which dents the new chart at number 90. Meanwhile, Shakira's seven-week reign atop the Hot Latin Songs chart has ended - Don Omar's ANGELITO has toppled the sexy Colombian singer's HIPS DON'T LIE. And the Red Hot Chili Peppers' DANI CALIFORNIA still rules the US rock charts - the track claims the top spot on Billboard's Modern and Mainstream Rock charts a 13th and 11th week respectively.
