We have no idea what's going on with Kate Hudson's ... umm downstairs ... but it's certainly odd.

The movie star donned a form-fitting unitard for a photo shoot for her workout line, Fabletics, on Tuesday and while the blonde actress' body looked on point, her nether regions were left a bit ... uh, exposed. It almost looks like she's wearing a cup. Is that possible?

At one point, the photographer tells to pull the unitard down -- the leotard was looking a bit overly-bodycon. Maybe Kate needs to call Khloe Kardashian to get some tips on how to embrace her camel toe?
