Angelina Jolie's father has given an update on how she's doing in the wake of her shock split with Brad Pitt.

This will be Jolie's first Christmas alone with her and Pitt's six kids - Maddox, Zahara, Pax, Shiloh, Vivienne and Knox - after she filed for divorce in September.

While the breakup has undoubtedly been hard on everyone, when asked by E! News for an update on his daughter, Jon Voight, 77, replied: "She's OK. She's holding on."

The actor also revealed that he was planning to spend the holidays with Jolie and his grandchildren.

"Christmas is family, and I have lots of family. I'm hoping to see my grandchildren. I'm hoping to see my grand-nieces and nephews and be with them. I'm making the plans now," Voight said, while posing on the red carpet at the Critics' Choice Awards.

"By the way, I'm supposed to be making these plane flights right as we speak."

Jolie, 41, is currently maintaining physical custody of the estranged couple's six children, while Pitt, 52, has "agreed upon therapeutic visitation."

It comes after Jolie sent a none-too-subtle message to her estranged husband, filing court documents earlier this month to make their temporary custody arrangement public - even though nothing had changed since it was struck in October, according to documents obtained by People magazine.

Days later, a judge rejected Pitt's counter-request to seal the details of the custody dispute.
