Katy Perry and Orlando Bloom are wacky! The engaged couple hit up West Hollywood hotspot Craig's Monday night -- Katy decked out in a bright orange flight suit, looking like she's a NASA astronaut or something. She was carrying her leftovers in what looked like a lunch box as she hopped on the back of fiance Orlando Bloom's motorcycle.

The pair love going undercover, so a bike is the perfect way for them to travel so they have the excuse of wearing helmets to hide under!
