The dueling exes had accused each other of violating their divorce settlement. It was reached after architect Peter Cook admitted to having an affair with a 19-year-old babysitter.
On Tuesday, Brinkley and Cook told a state Supreme Court justice they had resolved their legal issues.
The specifics were not discussed in court.
Their nasty divorce trial ended in July 2008 with the out-of-court settlement.
Brinkley, a former Sports Illustrated model, got custody of their two children and kept property. He received $2.1 million from Brinkley and liberal visitation rights.

RIVERHEAD, N.Y. (AP) _ An attorney for Christie Brinkley's ex-husband says they've been discussing a proposed settlement in their court spat over details of their 2008 divorce.
Brinkley's attorney, Peter Caronia, issued a statement early Tuesday saying a settlement had been reached. That was just hours before the factions were due to face off in a Long Island courtroom.
Later, an attorney for ex-husband Peter Cook, James Winkler, insisted nothing had been set in stone.
Caronia's statement claimed there was an agreement denying Cook's requests _ including anger management for the former supermodel.
