has regained visitation rights of her sons, Preston, 2, and Jayden James, 1, PEOPLE has learned.
The singer on Saturday was spotted driving with her children in Studio City, Calif., in her white Mercedes convertible, which was decorated with pumpkins on the dashboard.
A presumed court-appointed monitor was seated in the front seat, with her sons in the rear.
On Wednesday, L.A. Superior Court Commissioner Scott Gordon had temporarily suspended her visitation rights. A source close to Spears told PEOPLE the judge removed her rights after the pop star was unreachable by a cell phone designated for court-related scheduling.
On Thursday, Kevin Federline's lawyer, Mark Vincent Kaplan, said he expected Spears would get visitation reinstated soon
because "she has complied with the part of the order [causing the suspension]."
Lawyers for both sides did not respond to calls for comment.
Spears and Federline are both required to show up for their next hearing on Oct. 26.
