Update: Oops, she did it again. One week after big sister Kim Kardashian-West debuted a fresh new bob haircut [1], Kylie Jenner followed suit, posting a clip of her own chop to Instagram stories on Sunday night.

While it's still TBD if the star's look is the real deal or the works of a wig, the copycat cut looks great – and (unsurprisingly) on trend [2]. Check out the photos ahead.

Kylie Jenner and Kim Kardashian [3] share more than genes and an affinity for cosmetics – now they also share the same hairstyle. In May, Kardashian's hairstylist Chris Appleton [4] chopped her hair into a blunt and sleek bob [5], and it looks like Jenner has followed suit.

Over the weekend, the social media star and entrepreneur celebrated her friend Anastasia Karanikolaou [6]'s 22nd birthday and posted a series of photos to Instagram with coordinating neon-pink swimsuits [7] and also a new bob haircut [8] that looks just like her big sister's.

Check out her chic new hair ahead . . . before she switches it up again.
