Rob Lowe's former nanny Jessica Gibson says he exposed himself

Jessica Gibson, 24, worked for Lowe and his wife, Sheryl, off and on for seven years, according to an 18-page document filed Monday in a Santa Barbara, Calif. court. Gibson quit on Feb. 24.

Lowe, 44, the lawsuit further alleges, "placed his hand inside Gibson's pants" several times from about Sept. 2005 to around Jan. 2008.

In a statement read on Tuesday's Today show the Lowes' attorney, Stanton "Larry" Stein, said: "Ms. Gibson's older sister worked for the Lowes for 7 years. Ms. Gibson worked for the Lowes on and off for 7 years. She left at least 2 times, to pursue other jobs, and returned each time asking for more hours. She sent 2 emails the day after she left, both saying she loved the Lowes and her leaving had nothing to do with them but her heart wasn't into being a nanny anymore.

"This is totally inconsistent with her latest allegations," Stein added. "An investigation of dozens of present and former employees has failed to find one single person to verify her allegations. The allegations in the complaint are simply untrue."
