He previously spoke about gaining weight for the crime comedy War Dogs, later calling one of his celebrity pals for tips on how to tone up after filming.<\/p>\n \u201cThe idea that the media tries to play me by stalking me while surfing and printing photos like this and it can’t phase me anymore is dope,\u201d he continued. \u201cI’m 37 and finally love and accept myself.\u201d<\/p>\n Keep reading to see more stars who have undergone major weight loss transformations\u2026<\/p>\n More from E!

We introduced him always to the gym and all of that kind of stuff. And then, out of nowhere, he decided that he wanted to be lean. And now he is.
