Imitation is the ultimate form of flattery, right? The Backstreet Boys are changing things up on their concert cruise and making things really, really, really wanna zig-a-zig-ah.

During their Backstreet Boys Cruise on Tuesday they threw everyone for a loop by dressing up as the iconic girl group, The Spice Girls. Each guy took on one of the ladies' famous outfits and instantly became Posh, Ginger, Baby, Scary, and Sporty Spice just for the night.

"Celebrating all of the girl power that's kept up going for 25 years," the boy band wrote on their Instagram post, while paying tribute the millions of fans from all around the world.
