It's been a month since the media mogul Kim Kardashian went blonde but the reason behind the 36-year old star getting on the lighter side wasn't known until she revealed it on Instagram on Tuesday.

Kim revealed she was among the stars who revisited the modern version of platinum blonde. The whole new vibe and silver-tone was "For The D" Challenge she told on her social media platform

A snap of her wearing a tiny sports bra with gray sweatpants and nude booties to go with the casual look was captioned "I'd go blonde for that D."

 I’d go blonde for that D...

A post shared by Kim Kardashian West (@kimkardashian) on Oct 3, 2017 at 2:27pm PDT

According to People magazine , By saying "For The D", she referred to the viral craze, a challenge where people are found rapping about the things they would do to get some sex.

It was her lewd X-rated joke on Kanye West referring to the challenge and Khole Kardashian comment in response "You're sooooo obsessed with that D," added fuel to the fire. Kim in an interview, in 2014, said that Kanye West liked blonde hair.

"I was talking about this yesterday actually with Kanye. He asked if I would ever go back to blonde," she says. "I was like, 'Not right after a baby because my face was so swollen and it looked like my lips were huge. My face was just off.'" she said.

Last month Kim's hairstylist gave her a spin of silver tone and since then Kim has been documenting about her High-Maintenance hair on her social media platforms. She is obsessed with her new blonde locks and her hairstylist Chris Appleton, who is, running from pillar to post to nail the look, every time.
