What do you get when you mix Las Vegas and Hollywood? Britney Spears, of course!
The "Hit Me Baby (One More Time)" singer, who's currently in residence in Sin City, attended the Elton John Oscar party on Sunday looking as if she just stepped out of one of her own shows.
You want to read about the dress? Well, it was cleavage-baring (as you do in Vegas), sparkly and black with a nude underlay.
A gorgeous metallic necklace that was half choker, half rope-style hung around her neck which gave people plenty of opportunity to eye her bling.
Naturally, the brunette/redhead didn't show up alone: boyfriend David Lucado stayed close to Justin Timberlake's ex for the evening.
So many gorgeous dresses at the Oscars:
