The TALENTED MR RIPLEY actor has agreed to spend Christmas morning with Frost and their children RAFFERTY, IRIS and RUDY, and Frost's son FINDLAY from her previous marriage to SPANDAU BALLET star Gary Kemp.
But the pair will go their separate ways again later in the day when Jude returns to the home he shares with new lover Sienna Miller, whom Frost has banned from ever entering her house.
A source close to the former spouses says, "Sadie is so relieved that she and Jude are on more civil terms but she draws the line at playing hostess and being all chummy with his new girlfriend. She and Jude have been speaking again and hopefully the worst of the bitterness is behind them.
"Christmas day will be the first time they've all been together since the divorce started in February. They have made a pact not to argue or say horrible things to each other in front of the children."
