Who cares? Christina used to walk around with her **** exposed all the time during her Stripped days.... When it was much much more frowned upon than it is now.
For fun. Because she may not have the opportunity to do these types of things in the future. Because she loved to experiment with fashion and modeling. Idk there are a lot of possible explanations
Meh. Boobs are boobs. Kids suck on them from Day 1. Gay, Lesbian, Straight Women/Men love Boobs. I can't think of anyone who hates boobs in general (like certain boobs are just ugly) but I don't see why they are such a problem.
She's just dressing how she wants, and has basically proven it isn't classless to show a bit of nippppple.
I'm so glad my fave is young and beautiful and not beastly looking and can pull off looks like this with the whole fashion community fawning over her every move. Queen Rih.
