We told you yesterday that Ryan Gosling left the Peter Jackson-directed film adaptation of The Lovely Bones this weekend, but now The Los Angeles Times is reporting that a little chub might have been the reason behind those so-called "creative differences."

Peter Jackson was said to be quite surprised that Gosling had showed up to start work on "The Lovely Bones" looking like he'd donned a fat suit. According to sources, the 26-year-old Gosling had apparently told the director he was going to gain weight to age himself up to play the part of a grieving father, but Jackson was still expecting some movie star allure -- not paunch and a beard. By Friday, Gosling had left the high-profile production over those pesky "creative differences," and, by Sunday, he'd been replaced by 36-year-old Mark Wahlberg, who actually could be old enough to father a teenager.
