Honestly though, Lindsay Lohan and MK Olsen do look a lot older than they should due to losing hydration and elasticity in their skin from smoking and whatever else they have done, but saying Scott looks like Kourtney's uncle is messed up. He looks and even acts younger than her. Maybe its her lavish lifestyle, her busy lifestyle helping her sister and mother attract as much attention as they can, but I don't see the younger than Scott thing at all. Olivia, Chris Hemsworth, ScarJo, ERWood, Cavill, Lutz, Hammer look like they 'could' be older, but at times their faces reflect a certain 'jeunesse' feature to it that makes you realize they are in their 20s. I can see why people look at Adele, Flo, and definitely Lil Wayne as way older, but once again, it could be whatever they eat, drink, smoke etc.. Even Lady Gaga and Megan Fox can look in their 20s, but I seriously think dieting and hardcore workout regimens can do more damage than good. I think Khloe does look her age. Her sisters faces are more harder, while hers has a bubbly-like persona to it.
