Kim Kardashian, who has the highest number of Instagram followers, went on a tweeting rampage on Friday and shared an old photo of herself on Instagram wearing only lingerie.

In the photo, the 31-year-old socialite kneels on a white chair wearing black bondage-inspired lingerie with black knee-high boots and has long, blonde hair, Us magazine reported.

The TV reality star seemed to credit her hot bod to being on a gluten-free diet as she captioned the image “Gluten free is the way to be…Oh Hi.”

She last had blonde hair in August 2010 and has since tweeted new photos of herself proving she still has dark locks. In one close-up shot, she wrote, “I’m bored.... Oh hi!”
