Christina Aguilera is "business as usual" in a jaw-dropping skin-tight leather getup. The 40-year-old singer and reality judge big-time upped her leather and designer game this weekend, posting for her 7.5 million Instagram followers and parading her fierce figure in a statement all-black look. The "Just A Fool" hit-maker, who is fresh from releasing a PRIDE merch line, went straight for the Dior and Fendi, also wowing fans with her bad-girl and slightly Matrix vibes.
