Shanna Keeps Nanny on the Down Lowe

One of the nannies filing suit against Rob Lowe was served papers at Shanna Moakler's home -- but Moakler stonewalled us when we tried asking her the dirty details.

She was out with Travis, who claimed he didn't even know who Rob Lowe was. Must not be a "Brothers & Sisters" fan.
