Here's one possible reason why Britney Spears hasn't answered all the court's phone calls for drug tests: she's got a no. 1 album on her hands! Yes, despite being eclipsed by The Eagles for no. 1 on Billboard's U.S. charts, Spears apparently still has what it takes abroad. The "Gimme More" singer finished last week as the no. 1 seller on Billboard's European and Canadian charts, and took the top spot in U.S. digital downloads as well. Take that, Eagles! Spears' record company, Jive, is already prepping the official release of the album's second single, "Piece of Me," produced by the people behind "Toxic."
