LaBeouf blames lifestyle differences for split with Mulligan

Shia LaBeouf and Carey Mulligan split because of incompatible "lifestyles".

The 26-year-old actor dated his 'Wall Street: Money Never Sleeps' co-star for just over a year until October 2010 and though they were smitten when they got together, LaBeouf doesn't think their relationship would have lasted because they were such different people.
