How are you going to use photoshopped pictures for some, candids for others, and black and whites for the rest?
Sit your ass down.
Xtina's is the only candid-ish. She's at a red-carpet so full force make up is obviously present. The rest are from music videos and/or photoshoots. I thought if I used paparazzi shots, it'd be unfair since not everyone wants to look their best at all times.
