The actor and actress, both 42, detailed their plans in an interview with Us Weekly at the Save the Children Illumination Gala on Wednesday. Affleck and Damon are well known for their longtime friendship, and regularly celebrate holidays together.
"My mother is staying with us now and we'll all go down the street to Matt Damon's house," Affleck shared. "We're all invited. Matt and my family are all like one big extended family for Thanksgiving. I'm looking forward to it a lot."
"This year we're going to Matt's house, but usually I cook and Casey [Affleck] and his family come over," Garner added. "This year Casey is going to be in Boston and we'll be home. I'll still cook some stuff. Ben and the kids want me to take my grandmother's sweet potato pudding, so I'll make that."
Affleck and Garner married in June 2005, and have three children: eight-year-old Violet, five-year-old Seraphina and two-year-old Samuel. Damon, meanwhile, wed Luciana Barroso in December 2005, and the couple have three daughters: eight-year-old Isabella, six-year-old Gia and four-year-old Stella.
Affleck and Damon have been friends since childhood, and came to fame with their 1997 film Good Will Hunting. Affleck went on to star in such films as Armageddon, Pearl Harbor and The Town, while Damon landed lead roles in the Ocean's Trilogy and Jason Bourne series.
Affleck will portray Batman in Batman v Superman: Dawn of Justice and The Justice League films. He is also scheduled for The Accountant and Live by Night, while Damon will next appear in Ridley Scott feature The Martian.
