Lauryn Hill's former guitarist has filed a lawsuit against the singer alleging she has failed to pay him for work on a 2007 tour of Europe.

Jay Gore is demanding $20,000 and uses his suit, obtained by TMZ.com, to expose Lauryn Hill's alleged diva antics backstage.

The guitarist claims for former Fugees star "exhibited the type of behavior for which she had gained public notoriety which contributed to a hostile work environment."

He adds, "After shows, Hill would demand that the musicians and road support personnel attend meetings where she would engage in a person-by-person critique and berating.

"At one point, Hill made a statement in front of the tour personnel to the effect that 'I can't believe I am paying you fools, you should be paying me.'"
