BRITNEY PUTTING VOODOO HEXES ON HATED EXES!

BIZARRE Britney Spears is putting her obsession with voodoo to chilling use, according to insiders who dish the Toxic singer is casting hexes on her hated exes.

Spies claim the 41-year-old thrush is targeting Irish screen hunk Colin Farrell, teen crush Justin Timberlake, her boyfriend, childhood pal and ex-hubby, Jason Alexander and Kevin Federline, who she divorced in 2007 after three years.

"She's so sick and tired of Jason always trying to attach his name to hers to get attention because they were only married for 55 hours in 2004. And she's furious with Kevin, saying all he does is take, take, take,” dishes an insider.
