Christie Brinkley has filed a request for a temporary restraining order and a motion for post-judgment relief against her ex-husband Peter Cook, a Suffolk County, N.Y., official confirms to PEOPLE.
The motion was filed Wednesday – two days before Cook's revealing interview with ABC's Barbara Walters
is set to air.
Cook, 49, who has admitted to having an affair with an 18-year-old assistant and an online pornography habit, told Walters during his interview for Friday night's 20/20
broadcast, "I'm not the ... pervert that I've been painted to be."
The restraining order would prevent Cook from seeing his children and is not to keep him away from Brinkley, a source close to Cook tells PEOPLE.
"She's upset because the kids are seen in footage during the 20/20
interview," the source says.
Cook last saw the children when they had dinner on Wednesday night, and they are scheduled to be together this weekend, the source says.
Brinkley and Cook halted their messy divorce trial in July when both parties announced a settlement deal. The judge in the case, Mark Cohen, signed their final divorce decree Sept. 29.
The new motion is on the court calendar for Oct. 29, but the court official said it's unclear at this point whether the parties will actually appear in court or if their lawyers will simply submit statements to the judge in writing.
