Maroon 5 and Christina Aguilera Hit #1 on the Billboard Hot 100

Maroon 5 and Christina Aguilera now have the number one song in the US of A. Their collaboration "Moves Like Jagger" has jumped 4-1 to become Maroon 5's second chart-topper, their first was "Makes Me Wonder" in 2007 while it becomes Christina Aguilera's fifth appearance at the #1 spot and the first time in ten years! Her last time at #1 was also a collaboration, "Lady Marmalade" in 2001. "Moves Like Jagger" has sold over one million downloads.

Foster the People's single "Pumped Up Kicks" climbed 7-3, reaching a new peak. Hopefully this will be the next song to hit the top of the chart.

Katy Perry, who had the number one last week with "Last Friday Night" nearly dropped out of the top five this week, plummeting to #5.
