Britney Spears stole the show yet again on The X Factor Dec. 5.
The 31-year-old judge wowed the audience by wearing a sexy, form-fitting black Herve Leger dress. With her midriff partially exposed, the tanned âScream and Shoutâ singer wore her long blonde hair in loose waves. Spears completed her look with Erickson Beamon earrings and Yves Saint Laurent pumps.
During the Pepsi PreShow Live, the betrothed beauty shared new details about her 8-week-old puppy, Hannah. âSheâs 1.8 pounds. She is a barker! She is feisty and she will let you know when sheâs upset,â Spears said. âAnd she always wants mommy!â
Spears often dresses her pooch in adorable outfits. âI love this store called Fifi & Romeo,â she explained. âItâs ridiculously expensive but itâs fun.â
Later that night, Spearsâ two remaining acts â Carly Rose Sonenclar and Diamond White, both 13 â performed two songs each. Sonenclar, whoâs been in the No. 1 spot for two consecutive weeks, performed Justin Bieberâs âAs Long As You Love Me.â
âYou sang it better than Justin did,â judge Demi Lovato, 20, told Sonenclar. When she performed Beyonceâs âIf I Were a Boy,â Spears told the young musician that she is âthe definition of The X Factor.â

White sang covers of James Brownâs âItâs a Manâs Manâs Manâs Worldâ and Rihannaâs âDiamonds.â âSo proud of Diamond and Carly tonight,â Spears tweeted. âWow, wow, wow.â
