The German supermodel separated from the 'Kiss From A Rose' hitmaker last January after almost seven years of marriage and filed for divorce in April.
They have three children together, and the singer also adopted Klum's eldest daughter, Leni, from a previous relationship, reported Daily Star.
The split recently turned nasty when Seal criticised his former partner for embarking on a romance with their former bodyguard, but they look set to put the animosity behind them this Christmas.
According to reports, the former couple has made peace and will spend the holidays together in Los Angeles to keep the kids happy.
"They're trying to be co-parents and show up for their children," a source said.
