Time for the kid sister to get her own thread (who's even hotter than Gigi, IMO). ;)
Agree to disagree. Not just because of the bellybutton thing, but also because Gigi's facial structure is just more appealing. Bella's face actually makes her look more like Jennifer Lawrence's kid sister.
Neither of them are genuinely facially attractive to me (though Gigi probably edges out in that category); Bella seems to be a bit curvier to my eyes, which wins out for me... well, yeah, and the fact she has a shallow innie instead of an outie.
