Hip-hop mogul Timbaland has fought off a late charge from Avril Lavigne to keep the number one spot on the US pop charts. The hitmaker's Give It To Me hit, which features Nelly Furtado and Justin Timberlake has scored a second week atop the Billboard Hot 100. Akon's former chart-topper, Don't Matter, remains at two, while Lavigne's Girlfriend jumps up from six to three on the new countdown. Fergie's Glamorous and Gwen Stefani's The Sweet Escape round out the top five, at four and five respectively. The Hot 100's top debut is Fall Out Boy's Thanks Fr The Mmrs, which enters the chart at number 67.
