Maybe Blondes Don't Have More Fun? Kim Kardashian Debuts Brunette Hair (Again), but Is It Real?

Reality star appears to have changed her tresses once again

Kim Kardashian can't seem to make up her mind when it comes to her hair!

She has gone from brunette to blond, back to brown and blond again in a blink of an eye! But despite seemingly settling on her new platinum 'do, Kim has [maybe] changed her coif once more. One of her go-to makeup artists Mario Dedivanovic Instagrammed a picture of what looks to be Kim on set. Although it's a picture of her backside, you can tell by the enviable curves just exactly who it is.

"Brunette vibes today on set guess who? #MakeupByMario," he captioned the pic.

Hairstylist Jen Atkin also Instagrammed a picture of life on set with the famed makeup artist, captioning a stoop picture, "Stoop Glamstorming (glam brainstorm session) w @makeupbymario & @reneluv today on set w @kimkardashian. (Note Rene's shoe game)."

Whether or not it's a wig or she's back to brown, Kim seems to have called "dibs" on the peroxide plunge! Kylie Jenner, who became so known for her constant hair transformations that she released her own line of extensions, told E! News that she won't go platinum because she doesn't want to seem like a poser.

"I would go that far," Kylie said of her big sister's extreme hair change. "But it's her thing now, so I don't wanna copy her!"

For those who look forward to watching Kylie continue to change her tresses, rest assured, she told us she'll "find something else, I'm sure."

As for Kim? We're thinking the darker 'do is a wig for something she's shooting, because she recently dished that dyeing her hair platinum was a result of her frustrations with trying to get pregnant for a second time. Even though she has done everything "so perfect to try and get pregnant," none of it seems to be working, so she's going to try going about it incorrectly.

"I'm going to do everything that I want to do and that includes going platinum," she told E! News' Ken Baker while promoting her Glu Mobile app game. "Hopefully I will get pregnant doing all the wrong things. I'm totally changing my tactics."

She added of her video game and pregnancy woes, "Maybe we should set up a fertility clinic and a girl has to go every single day for over a year and get so frustrated. I'm over it. I'm over trying, overthinking it, hence why I dyed my hair blond."
