Who: Britney Spears and Khloe Kardashian.
What: Having a red-faced red carpet fashion moment both wearing almost identical high-neck black jumper dresses to the same X Factor finalists party.
Where: The SLS Hotel, Beverly Hills, 5 November.
Verdict? In the LBD style wars, we've got to crown Khloe the winner; not only are we in love with her metallic silver stilettos, we prefer her hair and make-up, too. Sorry Britters.
Perhaps the X Factor USA stars' stylists could have a little tête-à-tête before the next party?
