Nanny Claims Rob Lowe's Wife Sexual Harasser

A second nanny in the Rob Lowe case has filed a cross complaint, and this one is ugly.

Laura Boyce is not accusing Rob of sexual misdeeds, but she's throwing everything -- including the kitchen sink -- at his wife, Sheryl.

TMZ is privy to the complaint, which has been filed in L.A. County Superior Court, but not yet released. Among the allegations against Sheryl:

- Walking around naked, completely exposing herself to Boyce.

- Asking Boyce about the size of Boyce's boyfriend's penis.

- Asking questions about how she could have sex with Boyce's boyfriend, given his 7' height (he's a former NBA player).

- Using her forearm to gesture the size of Boyce's boyfriend's penis.

- Once saying "laughingly that her husband's (Rob) cockrings were broken," allegedly showing them to Boyce.

- Telling Boyce about her sex life with Rob.

- Talking about the size of her children's penises.

- After Boyce allegedly phoned to say she wasn't coming to work because she was sick, Sheryl allegedly screamed Boyce "got strep throat from sucking ni***r d**k. I mean black d**k."

There is no claim of unwanted touching or overture. There are also claims for wrongful termination, abuse of process, unpaid salary and labor code violations.

UPDATE: Larry Stein, the attorney for the Lowes, issued the following statement to TMZ: "Having struck out against Rob Lowe, Gloria Allred now seeks to drag his wife and children into the fray. In response to a lawsuit against Laura Boyce by the Lowes, Ms. Allred filed a cross-complaint on behalf of Boyce, which contains false allegations, in an apparent attempt to divert the negative publicity which Allred's client, Gibson, has universally received.
