Former Nanny: Rob Lowe exposed himself to me

Rob Lowe's former nanny claims the actor frequently exposed himself to her during the seven years she worked on and off for him and his wife, Sheryl, according to a lawsuit filed Monday.

24-year-old Jessica Gibson -- who resigned as the Lowe's nanny February 24 — also claims the actor, 44, "placed his hand" inside her pants several times between Sept. 2005 and Jan. 2008.

Gibson claims Lowe groped her butt without her consent and that his wife Sheryl would walk around the house naked and make vulgar comments about their sex life, according to the 18-page document.

In a statement read on Tuesday's Today show, while Gibson was being interviewed with her attorney Gloria Allred, the Lowes's 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. An investigation of dozens of present and former employees has failed to find one single person to verify her allegations.

"The allegations in the complain are simply untrue."

Allred immediately shot back: "We don't think so."

Asked why she returned to work in the household, Gibson answered, "I love the children. I needed the job. I thought it would get better, and I was scared."

Lowe came clean about the suit on the Huffington Post last week, claiming that the nanny was falsely accusing him of inappropriate conduct in order to get $1.5 million in "hush money."

"My family is devastated at this betrayal," he wrote. "This woman worked in our home and traveled with us off and on for seven years, without complaint."
