That was fast! After a brief stint as a brunette, Britney Spears made the switch to a bold red hue late last week. While the star has never been a redhead before, we have seen her in two very similar looks -- back in 2003, Spears showed off a dramatic fire engine hue in her "Toxic" video, and later donned an auburn wig with blunt bangs for the "Womanizer" video in 2008. Six years later, the singer's crimson hair has made a comeback, and is still flattering as ever. Besides, we're sure the shade helps her get into character by the time she plays "Toxic" each night at her Las Vegas show!
