Jennifer Lopez had a busy weekend promoting the heck out of Samantha Thavasa, but she's back on home turf and looking better than ever! Jennifer got off the plane at LAX wearing an all-grey ensemble after telling a Tokyo crowd that her children "come before everything." She also promised to get her nails done in the "Japanese style," but since I'm not quite sure what that is, I can't tell you if she went through with it!
