Paris Hilton and Nicole Richie stun in slinky dresses as they attend 10th Annual Vulture Festival in LA

Paris Hilton and Nicole Richie looked gorgeous as they attended the Vulture Festival in Los Angeles over the weekend.

The former Simple Life co-stars, both 43, coordinating in long-sleeved, snug-fitting maxi dresses for the occasion.

Hilton — who recently celebrated daughter London's first birthday — opted for a black dress covered in a grid of sparkly stones.

Meanwhile, Nicole wore a mock neck red variety, showing off her slender frame.

The women posed together on the red carpet before joining a panel discussion called How It All Began.

Paris accessorized with a thick black choker and wore her long blonde hair with a fine and precise center part, letting the locks fall over her chest.

Meanwhile, Nicole's shoulder-length dirty blond tresses were equally sleek and were also parted down the middle.

She wore a gold necklace with a round, red stone accent and added matching bangles.

Both ladies looked typically beautiful with meticulously applied makeup accentuating their features.

Hilton wore shimmery, warm-toned eyeshadow and finished her flawless look with a mauve, matte lipstick.

Earlier this year the socialites got to work filming their The Simple Life reboot series at a Sonic Drive-In in California.

In July Paris appeared on social media to tease the upcoming series, which celebrates the 20-year anniversary of the comedic reality series.

'Hey guys, just got home from shooting with Nicole,' she said in a video shared on Instagram.

'As some of you may know, we are doing a reunion special to celebrate 20 years of our show,' she said at the start of the clip.

'It's been so much fun and we're planning something very, very special and I thought the best place to find the people that I would want to be a part of this is here,' she continued as she engaged with her millions of followers.

Paris went on to invite fans to share what they loved about the original TV show, highlighting their favorite episodes and scenes.

She encouraged her viewers, 'We love watching your TikToks and when you guys use the different sounds from the show and dressing up as us on Halloween.'

'That show was so special. The best memories ever. It's such a huge part of our life and we love our fans so much so we wanted you guys to be a part of this,' the mother-of-two gushed.

Hilton wrapped up by exclaiming, 'I'm so excited to be doing this with Nicole on Peacock,' she said, noting that the streaming service is also home to her series Paris in Love.
