Yep, we're talking about cleavage. Britney Spears opted for a plunging neckline that put her girls on full display, but noticeably absent was the push-up bra, which actually would have made a world of difference.
As for Kim Kardashian, we're not sure what kind of bra she was sporting (and now that we mention it, it feels a little creepy that we're even wondering), but whatever, her boobs looked great and we're not afraid to say it. She also wasn't afraid to show them off, posting this sexy selfie on Instagram that was maybe a little off-center...or was it?
While Kim may not have won an Oscar last night (although she did win a Razzie over the weekend), she does get our vote for "breast dressed." Congratulations.
