Jessica Gibson's sister worked for Rob Lowe

While Rob Lowe and nanny Jessica Gibson (pictured) are busy suing each other, People has done some sleuthing just in time to dig up more dirt for Gibson's photo shoot for the mag. It seems her half-sister Jamie had also worked for Lowe, according to their father, Jim Gibson. Not only that, but it seems Jamie was the one who introduced Jess to Rob, since Jamie was previously Lowe's nanny.

"I'm sure (Jamie) thinks if only she could go back and change things she would. But, she can't –- there's no point regretting the past," Jim says. "No one in the family wants her to think that way. What's done is done."

Jim also says Jamie (who has a different mother) left to get married, but wanted to quit anyway.

"She was happy to get out of there. She couldn't take it anymore. Nothing really bad happened like it did with Jessie, but Jamie was overworked and couldn't stand it," he says.
