Fans can't wait to see how Margot Robbie portrays Harley Quinn on the upcoming supervillain movie, "Suicide Squad."
Margot Robbie has been working hard on the movie, along with her other "Suicide Squad" co-stars including Jared Leto, Will Smith, and Cara Delevingne.
Various reports have been released about how allegedly crazy it is on the set of "Suicide Squad" - with the Harley Quinn actress getting bruises on her thighs and receiving a rat as a gift from 'The Joker' - things have purportedly been crazy enough to push their director, David Ayer, to get a therapist on board.
And according to a new report, Harley Quinn is not to be outdone by The Joker in contributing to the mischievous deeds around the set.
Apparently, Margot Robbie has been naughtily cheating - on her diet! According to Dish Nation, the actress purportedly "behaves like a naughty schoolgirl" and eats calorific grub whenever her trainer isn't looking.
"She's been training really hard for her role in 'Suicide Squad' but if she had it her way she'd have a cheat day every day," an insider reportedly told the website.
"She's forever messaging her trainer to get him to bring her snacks, but if he can't get there immediately or she knows he won't be around for awhile she'll head out and pick up a high calorie treat."
The actress has reportedly been putting in a lot of effort for her Harley Quinn stint, which includes getting a lot more exercise.
"She works out hard - because she kind of has to," the source dished out. "She's naturally got good genes but her appetite is insane!"
Margot Robbie has admitted in the past that she loves to eat fast food.
"I don't have a very good diet," Margot previously said, as quoted by Shape. "I love beer, fries, burgers, but if I have to get in a bikini then I'll eat carrot sticks for three days.
"I'm one extreme or the other. I'm not good at doing moderation. I get miserable if I don't eat. I can't just have a salad every day and a half a glass of wine every second day. Can't do it."
In June, OK! Magazine reported that industry executives are allegedly asking the "Suicide Squad" actress to cut off some pounds.
"If you think Margot Robbie is one stunning young lady, you are definitely not alone, but Hollywood execs want her to slim down!" the magazine reported. "The already petite actress has been told to drop an astonishing 20lbs in order to make it to the A-list!"
