Kim Kardashian hints at hair colour change as she is reunited with Kanye West in Paris

Kim Kardashian prompted talk among her fans that she was hiding something as she stepped out almost incognito in Paris. The reality TV star hid her trademark long locks under an oversized thick woollen beanie, causing celebrity watchers to speculate that she had returned to being blond.

A few wisps of very fair hair were seen poking out of her hat, in spite of Kim's efforts to conceal her tresses.

The lovebirds looked their usual stylish selves as they coordinated in black outfits. Kim, 34, flaunted her petite figure in tight leather trousers and a black top, keeping warm with a furry stole.

Her rapper husband, who has mingled with the likes of Karl Lagerfeld during Fashion Week, also added a layer to his dark ensemble with a fur-collared bomber jacket.

Kim announced that she had touched down in the French capital – a favourite destination for her and Kanye – on Thursday morning. The model shared a photo of the iconic Eiffel Tower on Instagram, captioning it: "And so it begins....Paris Fashion Week."

The couple will most likely be making an appearance at the Balmain show later on in the day, as they are good friends with the brand's creative director Olivier Rousteing.

Kim and Kanye were also crowned as the newest faces of Balmain's SS/15 menswear collection last December, and announced their collaboration with an edgy photoshoot campaign.

It wouldn't come as a surprise if Kim has indeed gone blond, and is planning to unveil her new hairstyle on the front row at the fashion show.

Her change in hair colour would come as a welcome surprise to Kanye, who has previously admitted that he prefers his wife with caramel or golden honey locks.

Kim's decision would also follow in the footsteps of her younger sister Khloé Kardashian, who revealed that she was "in love" with her new blond hair. The 30-year-old ditched her usual brunette locks in favour of a golden blond hue, and shared a snap of her new 'do on Instagram.
