The buzz about Leonardo DiCaprio's new film The Wolf of Wall Street is starting to get a little deafening. Everyone's talking about how many Oscar noms it's gonna get, how it's Martin Scorsese's best film in years and about its gorgeous leading lady, Margot Robbie. So, with the film in full force promo mode as we speak (it's out on Christmas day!), here's what you need to know about Hollywood's latest It girl.

1. The 23-year-old Aussie actress started her career on smash Australian soap Neighbours, where she played a main character, Donna, for three years. The show is also a hit in the UK. 

2. She then got her big break when she landed a role opposite Christina Ricci in Pan Am. We're still sad this got cancelled. Sob. But that didn't stop Margot, who later got a role in this year's Brit romcom About Time

3. She's fun/outspoken on Twitter and was unafraid to address those Will Smith affair rumors (they're starring together in the upcoming drama Focus) by tweeting, "It's disappointing that goofing around on set could be taken so out of context."

Oh, plus she's super pretty and stylish—as if you hadn't noticed. Go, girl! We can't wait to see more of this one.
