Australian actress Margot Robbie has already racked up quite the resume during her short time in Hollywood. After bursting on to the scene with her star making turn in Martin Scorsese's 'The Wolf of Wall Street', the blonde bombshell has bagged big roles in the upcoming live action take on Tarzan as Dr. Jane Porter and Warner Bros. and DC's super villain team up 'Suicide Squad' as the fiery Harley Quinn. She also has a role in Tina Fey's upcoming comedy 'Fun House'.

Now Robbie can add Elle cover girl to her list of accomplishments. In the August issue of the magazine, Robbie candidly shares some interesting tidbits about her career so far. She says that she's often mistaken for being older than she really is:

People seem outraged that I'm 24," says a bemused Robbie, referring to the horde of online commenters she tries but fails to ignore. "People think I'm a decade older." Part of that might simply reflect her facility as an actress. "Like a lot of actors who got their start on soap operas-Julianne Moore, Alec [Baldwin]-Margot makes great, strong choices but then is still very quick and flexible," says Tina Fey, who stars alongside Robbie in the upcoming Fun House.

Robbie also mentions that she has a pet rat which was given to her by her Suicide Squad co-star, Jared Leto. Leto originally gave Robbie the rodent as a prank while trying to prepare for his role as the Joker, the psychotic clown prince of crime. It seems that Robbie took a liking to the animal, and now cares for it like any other pet:

"Several crew members suggested killing it, but Robbie kept the rat because, "If Harley [her character in Suicide Squad] got something from Joker, she'd probably cherish it." Rat Rat now dines on organic berries from Whole Foods."
