ET has the latest...

ET has obtained another set of court papers related to ROB and SHERYL LOWE's lawsuits against three former employees. The latest papers relate to his lawsuit against former nanny JESSICA GIBSON.

In the papers, the Lowes accuse Gibson of breaching a confidentiality agreement; defamation; breach of duty of loyalty; breach of fiduciary duty; intentional infliction of emotional distress; negligent infliction of emotional distress, intentional misrepresentation; negligent misrepresentation; trespass and abuse of process.

The lawsuit stems from claims by the Lowes that Gibson "violated their personal space for her own sexual trysts," "[engaged] in illegal drug use while on the job," and "made false statements to others to suggest that she had a personal and intimate relationship with Rob Lowe," amongst other allegations.

Yesterday, Lowe blogged for the Huffington Post that "a former employee is demanding my wife Sheryl and I pay her $1.5 million by the end of the week or she will accuse us both of a vicious laundry list of false terribles [sic]." Gibson is presumably the nanny he wrote about in that post, as text messages quoted in the Web article match those cited in these court papers.

Earlier today, ET reported that Lowe and his wife had filed papers against another former nanny, LAURA BOYCE, as well as a former chef.
