Rob Lowe's legal battle against his former nanny, Jessica Gibson, is on hold, pending her appeal to a higher court to throw out his million-dollar lawsuit against her.
"Everything in the case comes to a halt for now," Gibson's lawyer Gloria Allred tells PEOPLE. "Although we were successful in getting parts of his lawsuit thrown out in an earlier decision, we feel most of it is still without merit."
The actor has accused Gibson, 25, of breaking her confidentiality agreement and spreading lies about him. At the time he filed his preemptive lawsuit, Lowe said a "former employee" – later identified as Gibson – "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."
A week later, Gibson countersued him
for sexual harassment, alleging the Brothers & Sisters star groped her and exposed himself over her seven-year employment with the Lowe family.
Lowe, 44, and his wife, Sheryl, 47, also preemptively sued a second former nanny, Laura Boyce, 38.
Boyce responded with her own sexual harassment claim against the couple, although she only accuses Sheryl of direct harassment.
Lowe's lawyer, Larry Stein, had no comment.
