Well, since you put it like that........ Hmm. I could've sworn that particular set (the pink bikini one) really highlighted how flat Miley's ass is. However, when I say Selena's filling out, I mean that she still appears to have a way to go, whereas Miley's probably done all her "growing" by now.

Note I only said flat-ISH. This pic highlights it better IMHO:



It's like her ass has taken on an unjustified mythical status around here, for what? Selena's just looks more perky:

I think it might be because of this

Understandable, but it's all down to angles. It's a great ass for sure, but it seems to be held on some kind of unreasonable pedestal when compared to true greats like Kelly Brook, Jessica Biel and Kim Kardashian.

Miley: she's rockin' some perfect curves and her stomach is incredibly sexy. Selina still has a couple years to go. Too up-and-down right now. I look at Miley and think one thing only: sex. I look at Gomez and think: "that's a pretty girl."

People are saying she has a better booty than Selena, not those 3. There's a vast difference. Hips/ass are Selenas two biggest flaws imo (as far as body goes).

Miley Cyrus in my book, especially due to her wonderful mound. Almost a mountain downthere, so sexy to look at

Selena has caught up in the breast department, and might even pass Miley in that area. Who knows, we might have to keep an eye on that!
