The top spot of this week's Billboard 200 is held by country singer Lady Antebellum, but Lil Wayne debuted right behind her with Rebirth ... while Grammy winners saw a sales boost.

In at no. 2 was Lil Wayne's latest, Rebirth, selling 176,000, a far cry from his last solo album, Tha Carter III, which opened with 1 million sold in 2008. However, the rock album did better than initially projected, reports Billboard, who estimated sales being somewhere around 125,000 to 150,000.

Later, Lady Gaga's The Fame dropped one spot to no. 4 with 79,000 (up 17%); while her Fame Monster EP dropped two slots to no. 12 with 34,000.

The 2010 Grammy Nominees compilation climbed three slots to no. 5 with 71,000, while Grammy performers and winners, the Black Eyed Peas, saw their The E.N.D. jump four spots to no. 6 with 70,000.

Outside the top 10 we have Michael Jackson's This Is It at no. 11 with 35,000, Alicia Keys' Element of Freedom at no. 13 with 34,000, and Beyonce's I Am ... Sasha Fierce rose 21 spots up to no. 14 with 32,000 copies sold.
