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.
