Golden Globe-winning actor Jason Bateman and his elder sister, Justine Bateman, may not meet often, but they share a strong bond and relationship. As cited by E! News, in a recent Esquire interview, 56-year-old Jason Bateman, in a light-hearted conversation, talked about his current relationship with Justine Bateman, who, besides being an actress, is also a film director and author.

Jason Bateman, who recently starred in the Netflix original series Black Rabbit alongside Jude Law, during his interview, admitted that while he does not see his sister, Justine, very often, that does not mean they are not on good terms. Jason said:

"There isn’t the typical ‘We see each other every Thanksgiving or every Christmas and our kids want to be together. There isn’t that. In a great way."

While the Horrible Bosses actor, Jason Bateman, who has been married to former actress Amanda Anka since 2001, with whom he has two daughters, Maple and Francesca, explained that his relationship with his sister is based more on mutual interest than typical familial obligations. Jason added:

"Our conversations are the rich conversations you would have with an adult friend, not the kind of petulant back-and-forth you might have with your adult sibling. We hang out, and we’re nice to each other because we respect one another as individuals regardless of the blood thing."

Amid Jason Bateman's Esquire interview, the internet is curious about who Justine Bateman's husband, Mark Fluent, is.

Justine and Mark share a son, Duke, and a daughter, Gianetta.
