Instagram snap: Kim K. tests blond = fun theory

Kim Kardashian is letting the light in.

The reality star made waves with last year when she stepped out as a blond, and after reverting to her natural brunette color she's again turning heads with a lighter look.

As she declared on Instagram Wednesday, "It's baaaaack!!!! #BlondeHairDontCare."

While at first some thought she'd once again colored her hair several shades lighter, the mom of one later admitted that her strands weren't the real deal.

"It's just a wig!" Kardashian confirmed. "Looks so real though right?"

We'll let you decide.
