One of the causes of Ben Affleck's rocky marriage to Jennifer Garner was the actor's alleged tendency to womanize.

Aside from their ex-nanny, Christine Ouzounian, Ben Affleck has also been linked to a few of his former co-stars in various showbiz projects.

There have been rumors that the Batman actor is purportedly setting his sights on co-star Margot Robbie, who plays Harley Quinn in the upcoming 2016 super villain movie "Suicide Squad."

"Ben has had the hots for Margot ever since he saw her in The Wolf of Wall Street," Woman's Day reported, as quoted by Inquisitr. "As far as Ben is concerned, Margot is the sexiest woman in Hollywood right now."

Ben Affleck has reportedly filmed a little part as Batman in "Suicide Squad," and there are speculations that he might have been impressed with the Harley Quinn actress on the set.

Was Margot Robbie one of the reasons why Ben Affleck and Jennifer Garner chose to file for divorce?

Though some may speculate that the Batman actor can freely pursue Margot Robbie now that he's no longer with Jennifer Garner, Batman might have to deal with one problem - the Harley Quinn actress' boyfriend, Tom Ackerley.

Ben Affleck may not be the only villain in Tom Ackerley and Margot Robbie's love story. It has also been rumored in the past that Will Smith, the Harley Quinn actress' co-star in "Suicide Squad" and "Focus" is also purportedly interested in dating the Australian actress.

However, it doesn't seem that Tom Ackerley has anything to worry about. Even Margot Robbie's mother, Sarie Kessler, is reportedly 100% on Team Tom.

"She loves Tom, he's the one, he's the man in her life, he's a gorgeous and delightful person," Sarie told Daily Mail Australia. "They were friends and met while she was living in London, five friends together rented a house in Clapham, they loved it."
