Sugarland is celebrating their first time at the top of the Billboard 200 album charts. The duo's third CD, 'Love on the Inside,' moves from No. 2 to the No. 1 slot in its second week.

Last week's No. 1, Miley Cyrus' 'Breakout,' swaps places with Sugarland this week. Billy Ray's little girl is now boasting sales of more than 534,000 copies of her first album as herself, without her Disney alter-ego 'Hannah Montana.' Sugarland's sales are close behind with more than 485,000 copies to date.
