Adele’s ’21’ Back at No. 1 on Billboard 200

Adele can not only sell records -- she's also on her way to breaking them. The songbird's sophomore release, '21,' is once more perched comfortably atop the Billboard 200 chart for the 13th week. The only album with more staying power?

The 'Titanic' soundtrack, which was no. 1 for 16 weeks in 1998, was kept afloat by Celine Dion's 'My Heart Will Go On.'

Since its No. 1 debut in March, '21' has sold 4.1 million copies, making it the best selling album of 2011 to date -- by a wide margin. Adele's sales more than doubled the No. 2 best selling record of 2011, Lady Gaga's 'Born This Way,' which has only moved 1.9 million copies.

Adele shouldn't get too comfortable just yet, though. Two weeks ago, Evanescence booted her from no. 1, and Coldplay's 'Mylo Xyloto' is expected to oust her from the top spot this week. However, if history is any indication, the Brit will have no trouble bouncing back.
