Lady Gaga - U.S. Pop Charts Still Going Gaga

LADY GAGA is still dancing at the top of the U.S. pop charts, scoring a second week at number one.

Her Just Dance hit took 22 weeks to get to the top of the charts last week and now it's staying there, keeping Beyonce's Single Ladies (Put a Ring on It) at two.

But Beyonce isn't grumbling - her tune scores a ninth week atop the Hot R+B/Hip-Hop Songs countdown and moves to number one on the Hot 100 Airplay chart.

Kanye West's Heartless jumps up to three on the Billboard Hot 100, while T.I.'s Live Your Life and Love Story by Taylor Swift round out the new top five.

Red Jumpsuit Apparatus score the week's highest debut - Pen + Paper enters the chart at 75.
