Red carpet rebel Kylie Jenner threw something of a style strop last night

After gracing the front of the current edition, last night the Kardashian-Jenners were out in force to celebrate Cosmopolitan magazine's 50th birthday.

For the striking cover-shoot, the family had worn crisp white shirts – so understandably for their red-carpet appearance they also synched up in similarly complementary attire. 

Except that the youngest member of the mega-famous klan decided to go out on a limb and do her own thing… either that or she didn't get the all-black memo.

Standing out from the crowd in a pale short skirt and matching top, the 18-year-old teamed her outfit with white accessories.

Meanwhile, her elder siblings and mother looked stunning in striking dark evening-wear.

Khloe, 31, wore a velvet textured skirt with a thigh-high split, nude Louboutins and a plunging V-neck vest. Kourtney, 36, opted for a glamorous Balmain halter-neck jumpsuit with clinched-in waist detail.

And a seven-months pregnant Kim, 34, had on her signature body-con dress and oversized coat combo – complete with a €2,650 Balmain chocker

Momager Kris Jenner, 59, also looked amazing in a black jumpsuit and statement accessories – including OTT earrings. 

And while her sisters also had slicked-back hair worthy of any red-carpet, a more casual Kylie wore her lightened locks loose and long around her shoulders.

Noticeably absent was, of course, Kendall Jenner, 19, who is away modelling in London at the moment and was unable to jet back to California for the bash.

Cosmo Editor-In-Chief Joanna Coles was on hand to blow out the candles on a giant birthday cake, while the likes of Ashley Tisdale, Jessica SzohrStefanie Scott, Kelly Osborne, Sarah HylandLeona Lewis, and Cody Simpson were all also in attendance.

Amazingly for a family that has rarely been out of the spotlight since the launch of Keeping Up With The Kardashians eight years ago, the current Cosmo edition is the first time all six women have appeared together on the cover of a magazine.
