Kim Kardashian is sporting long lighter locks once again.

The reality TV star's latest set of selfies, posted on Instagram, show off her stunning new blonde hair, which suits her perfectly!

The first photo Kim shared on Wednesday (June 25th) sees her pouting into a mirror while wearing a white bathrobe, with the famed stylist Serge Normant by her side.

"It's baaaaack!!!! #BlondeHairDontCare thanks to @SergeNormant," read the caption.

In the much closer second shot, the 33 year-old star posed with legendary stylist Carlyne Cerf de Dudzeele, flaunting her lighter highlights.

"On set today with the legend @Carlynecerfdedudzeele," she wrote along with the snap.

Going by the two pics, it isn't clear if the change in hairstyle is just temporary for the photo-shoot, but a source reportedly confirmed to Us Weekly that she hasn't dyed her more recognizable darker tone just yet.

The new do is actually "a wig and tons of extensions" for a shoot, the insider revealed.

Furthermore, the snaps also can't tell us if Kim is effected by the recent reports that claim she hasn't spoken to her younger brother Rob since just before her wedding to Kanye West on May 25th.

The 27 year-old sock mogul is even refusing to return phone calls and texts from his big other big sis, Khloe, who he was supposedly very close to.

Rob "has no reason to talk to Kim," a source revealed, adding that "they haven't been on good terms for a very long time."

Reportedly, Kim "hasn't bothered to even attempt to talk to him since returning from her honeymoon, [while] Khloé has sent him text messages and left him several voice mails," another insider said.

Adding, "Rob hasn't returned any of Khloé's phone calls or texts. He feels completely estranged from his sisters and family. He really isn't in a good place."

It looks like future episodes of 'Keeping Up With The Kardashians' could be interesting.
