BRITNEY SPEARS - RECORD LABEL BOSSES: `THAT'S NOT BRITNEY SINGING'

Officials at BRITNEY SPEARS' record label are urging fans not to be fooled by an Internet tune, which claims to be a leak of the pop star's new record. A new song on the YouTube website, which appears to be all about Britney's estranged husband KEVIN FEDERLINE, features a Spears sound-a-like, but bosses at Jive Records insist it isn't the TOXIC singer. On the track, called FED-UP, the faux-Britney sings, "You think you can walk all over me/And you think that I will just let you be/Now I'm going to do things differently." But a spokesman at Jive says, "It's not Britney."
