A bitter Britney Spears sat down for the 3.5 hour broadcast of the 2008 Grammy Awards on Sunday night, and the Grammy-winning pop tart had some interesting comments about the legendary duet featuring Tina Turner and Beyonce. (Video Here) While Brit loved the high-action from music icon Tina, the has-been jumped right on the chance to rip into Bey: “She sure knows how to toss her hair,” Britney is rumored to have stated. “Too bad she can’t dance as good as Tina — who’s old enough to be her grandmother!”

Can you say MTV Video Music Awards?! After Britney’s humiliating performance at MTV’s VMAs last fall, perhaps Britney should err on the side of caution when criticizing the dancing of someone who’s actually in shape.
