Mel - aka Scary Spice - was pictured in the see-through LBD as she left London's trendy Nobu restaurant with her husband Stephen Belafonte.
The Spice Girl had even copied Britney's scrunch-curled hair and smokey eye make-up.
Britney, 30, debuted the slinky lace dress 11 years ago at the MTV Video Music Awards, which was held at the Metropolitan Opera House in New York.
Considering she was just 19 at the time, 37-year-old Mel clearly has no body hang-ups!
