Age-defying Christina Aguilera, 45, throws it back to 2002 in hotpants and suspenders

The 45-year-old pop superstar, who originally shot to global fame with 1999's Genie In A Bottle, completely rebranded herself three years later for her heavily provocative album, Stripped – giving birth to her legendary 'Xtina' alter-ego. On Sunday (October 11), Christina graced MISTR's second annual National PrEP Day Celebration at The Abbey Food and Bar in West Hollywood, wearing a look she could've rocked 20+ years ago. The star let her lengthy blonde tresses cascade freely as she posed for photographers in thigh-high boots – and people think she looks fantastic.
