The two, along with several other celebrities, got exclusive invites to Dior's private party at L.A.'s nightclub Poppy. Bella looked stylish arriving at the party wearing a patchwork denim suit with a black headband.
Paris was spotted posing with Kathy Hilton outside before heading in to celebrate, which isn't weird at all considering their family history. They go way back due to Paris' dad, Michael Jackson.
Other celebrities at the party included Winnie Harlow, "Stranger Things" stars Natalia Dyer and Charlie Heaton, "Baywatch" babe Alexandra Daddario, Jesse Metcalf and more.
Dior held the event to celebrate the launch of their Lacquer Plump.
