Back in April, Will Smith took over Ben Affleck's role in Focus, and Kristen Stewart peaced out, citing too large an age gap between herself and Smith. (Smith: 44; Affleck: 40; awkwardness: 100.) Now the film from Crazy, Stupid, Love. writer/director duo Glenn Ficarra and John Requa has found a new love interest for Smith in Margot Robbie, an Australian actress who'll appear in Martin Scorsese's The Wolf of Wall Street. She beat out Olivia Munn, Michelle Williams, Jessica Biel, and Rose Byrne for Focus. Like K-Stew, Robbie is 23.
