Actress Margot Robbie, who played Leonardo DiCaprio's wife in the movie “The Wolf Of Wall Street,” says people do not believe she is just 24 years old. The Australian beauty is on the cover page of a popular fashion magazine where she also talked about her pet rat.

People seem outraged that I'm 24," the Australian beauty told Elle magazine. "People think I'm a decade older.” One reason could be that the actress starred with some of the most experienced actors in Hollywood at the beginning of her career. Her first movie was with DiCaprio and now Robbie is working with Tina Fey in the upcoming movie “Fun House.”

Robbie also revealed she can rap a Lil Wayne song and knows some of the lyrics by heart. The actress is an animal lover and admitted she kept the rat that her co-star Jared Leto gave while shooting “Suicide Squad.”

"If Harley [her character in Suicide Squad] got something from Joker, she'd probably cherish it," the actress said. Robbie has since named the rat “Rat Rat” and he is growing up eating “organic berries from Whole Foods,” the magazine said.

Robbie is not very comfortable talking about boyfriend Tom Ackerley. The actress met him on the set of the World War II movie, “Suite Française,” where Ackerley is an assistant director. "He was a third AD, he's now working as a second AD, and that's, yeah," Robbie said.

Robbie is one busy actress. The Aussie star is excited about her upcoming movie “Z for Zachariah” where she stars alongside Chris Pine and Chiwetel Ejiofor. The science fiction drama is based on the book of the same name by Robert C. O'Brien and is scheduled to hit theaters on Aug. 28. Robbie is also looking forward to “Suicide Squad,” which stars Jared Leto, Will Smith, Ben Affleck, Viola Davis and Cara Delevingne.
