Olivia Wilde went for a walk yesterday in LA. The actress, who's front and center in the new trailer for Cowboys & Aliens, is chilling near her home in the exciting run-up to the release of her Summer blockbuster. It's not all downtime for Olivia, though, as her social life has apparently been quite active. She's been linked to not one but two of Hollywood's most eligible bachelors, since splitting from husband Tao Ruspoli in February. Olivia and Ryan Gosling were seen in early March touring the aquarium in Cincinnati, where he was based while shooting The Ides of March. Rumors kept flying once Olivia returned to California and got her dance on publicly with Justin Timberlake, her costar in Now, just a few weeks ago. Olivia will soon trade the West Coast for the East to support a different project. She tweeted that she plans to attend the Tribeca Film Festival, where a short she co-produced named Sun City Picture House, based on the story of a young Haitian man, will debut next week.
