Rapper T.I. has stunned U.S. pop fans by returning to the top of the singles chart and toppling Beyonce.
The R+B star's Single Ladies (Put a Ring On It) replaced T.I.'s Live Your Life last week (04Dec08), but the hits have changed places again - and the rapper can now boast a sixth non-consecutive week at the number one spot.
Britney Spears scores the week's highest debut, at three; Circus, the title track of her new album, is the star's first top 10 debut ever.
Lady Gaga's Just Dance and T.I.'s Whatever You Like round out the new top five.
