Katy Perry has stopped Lil Wayne from scoring a number one debut on the U.S. pop charts.
The singer's Last Friday Night (T.G.I.F.) has scored a second week at the top of the Billboard Hot 100 as the rapper rockets into the top three with She Will, his new tune featuring Drake.
The song's success marks Lil Wayne's highest new entry ever on the chart. It's his fifth top 10.
LMFAO's former chart-topper Party Rock Anthem stays put at two on the new countdown. Maroon 5 and Christina Aguilera's Moves Like Jagger and Nicki Minaj's Super Bass round out the new top five.
