The 77-year-old actor adds that he will be there to support Jolie and his six grandchildren as he's been doing.
On Monday, Jolie filed for divorce citing irreconcilable differences, and lists the separation date as Sept. 15, 2016, according to court documents obtained by ET. The 41-year-old actress is asking for physical custody of their six children -- Maddox, 15, Pax, 12, Shiloh, 10, Zahara, 11, and twins Vivienne and Knox, 8.
An attorney for Jolie, Robert Offer, told the Associated Press on Tuesday that the decision was made "for the health of the family."
Voight, 77,did not attend his daughter's wedding back in August 2014, but did issue a statement after news broke of her very private nuptials in France. "It seems like it was a beautiful simple ceremony with all the kids involved," he said at the time. "Must have been a lot of fun. I am very happy for them."
He's also gushed over Pitt to ET in June 2013 after Jolie spoke out about her decision to have a double mastectomy to reduce her chances of getting breast cancer. "You want your children to be surrounded by love and I like Brad very much," he said.
Jolie and Pitt, 52, met in 2005 while on set of their film Mr. & Mrs. Smith, while he was still married to Jennifer Aniston. The last sighting of the two together was in July, when Pitt and Jolie took their twins out for a birthday breakfast at the Griddle Café in West Hollywood, California.
