The actress looked delighted at the event in New York - and can you blame her? An on point look and the cover of the mag's late spring issue.
The auburn star, who will be on screens in The Great Gatsby next month alongside the ever glam Carey Mulligan, Leonardo Di Caprio and Tobey Maguire (quite a cast, hey?), combined a gold and black patterned shift dress with a black fitted blazer.
And the all important accessories? Isla opted for some adorable black shoes with a golden rim and a little clutch bag.
We got amazingly excited when the posters for the upcoming blockbuster were revealed, and now we just can't wait to see Isla do her thing so we can get excited all over again.
