Martin County, Florida - Tiger Woods' legal battle with his ex Erica Herman took another twist after her lawyer on Friday filed court documents accusing the golfer of sexual harassment.

According to a Sports Illustrated report, Herman says Woods blackmailed her into signing a non-disclosure agreement after they began their relationship.

At the time, the 39-year-old was working as general manager at The Woods Jupiter restaurant owned by the athlete in South Florida, and court documents claim the NDA was "a condition to keep her job when she began having a sexual relationship with [Woods]."

"A boss imposing different work conditions on his employee because of their sexual relationship is sexual harassment," the filing continues.

This latest development comes on top of a lawsuit in which Herman accused Woods of kicking her out of the house they shared for six years. The golf legend allegedly tricked Herman into thinking she was going on vacation, only to be told at the airport that she was "locked-out" of the house and not allowed to return.

Herman is seeking $30 million in rent money, saying she had an "oral tenancy agreement" in place with Woods that should have kept her there for five more years, even thought they had broken up.

"Tiger Woods, the internationally renowned athlete and one of the most powerful figures in global sports, decided to pursue a sexual relationship with his employee, then – according to him – forced her to sign an NDA about it or else be fired from her job," Friday's filing reads.

"And, when he became disgruntled with their sexual relationship, he tricked her into leaving her home, locked her out, took her cash, pets, and personal possessions, and tried to strong-arm her into signing a different NDA."
