TAYLOR & BEYONCE'S BACKBITING BRAWL!

The dirty doings behind divas' public smiles

REIGNING pop princess Taylor Swift is being trashed by Beyoncé and her posse, who can’t believe the hip-hop hardcase is being overshadowed by the goody-two-shoes blonde, stunned music industry insiders tell GLOBE!

Sources dish Queen Bey’s seething with jealousy and her music mogul hubby, Jay-Z, stoked the fire by taking veiled public shots at Taylor during this year’s Grammys after Swift won her fourth Album of the Year award while his wife — who wasn’t nominated in ANY category — has NEVER won for best album!

Despite making billions and being a music legend, Beyoncé sees red over 34-year-old Swift’s soaring success, especially since she believes Tay-Tay “is an overhyped, sassy brat who bulldozed her way to the top by trash-talking her exes, sparking petty feuds and rolling out one-dimensional bubblegum trash that’s not as good as it’s made out to be,” a spy tattles.
