Can anyone make me look like Megan Fox?
I'd love to know how she did her eyebrows and what eyeshadow she's wearing

Not too crazy about the lips, though.
For brows, you might try Chanel's waxy eyebrow pencil. The taupe is a forgiving shade if you can't go darker, but darker would be better. They have two eyebrow pencils - the waxy and the powdery. You want the waxy.
You might try Anastasia's clear silicon stick over it, it does a beautiful job of making brows look wet and a little darker.
I think Clarins tinted moisturizer would do well to give the shine effect she has, and some color/coverage. If you have light skin, the gold is a beautiful shade (even for pinky pale). Or, get the darker if your skin works with it.
Skin needs to be well-moisturized for this look (or use the Clarins tinted moisturizer above). She has said also that she uses a Chanel illuminator a lot... they have a few varieties.. it is white stuff either in a tub as a paste or a little jar as a liquid. You put it on the forehead, the bridge of the nose (and probably strategically around the eyes) to get that glowy, diffused look.
A chanel black eyeliner pencil done on the inner rim of the top (and just on the outside, toward the edge) would probably do well for the lash-liner.
Try a Clarins velvety red lip pencil with no lipstick for the lips (smudge gently, dab with gloss if you want), or try a gentle lipstain. (Or maybe if any lipstick one of Clinique's terrific sheer ones.)
For the hair, take a shower, comb and do nothing.
