The Keeping Up With The Kardashians girl walked the red carpet in a champagne-coloured gown, which featured a dramatic flowing train.
Adding structure to the fishtail number was a corseted bodice, as well as asymmetric straps and satin belt detailing.
There’s no denying that Kylie looked seriously smokin’ in the design. Have you SEEN those curves?!
The 18-year-old was rocking a tousled down ‘do and had kept her make-up fairly simple, pairing nude lipstick with classic winged eyeliner.
She was joined in front of the cameras by pal Justine Skye, who showed off plenty of leg in a thigh-slit metallic dress.
A black choker, smoky eyeshadow and poker-straight purple locks gave the 20-year-old model a real futuristic vibe. Very cool.
But there was one person who Kylie didn’t pose with – her on-off boyfriend Tyga.
While the rapper was also at the event, he arrived alone.
We’ve gotta say, Tyga looked pretty dapper in a simple monochrome suit. But Kylie clearly wasn’t bothered by this.
She posted no photos of him on her Instagram page and according to sources, spent hardly any time with him inside.
This isn’t the first time Kylie and Tyga, 26, have headed to events separately in recent weeks.
Kylie shunned her man in favour of her sister Kendall on the AMAs red carpet last month, just days after confirming that they were ‘on a break’.
But she later told fans on Ellen that they were still together, helped him celebrate his birthday and wrote a gift guide for boyfriends on her website. Um, confusing.
Could last night’s antics prove that they’ve ended things for good? Only time will tell…
