Fangs for the memories.

Kourtney Kardashian came ready to bite at stepson Landon Barker’s “Vampire’s Ball”-themed 23rd birthday party in a black lace slip dress and a trickle of faux blood dripping down her chin.

The Poosh founder, 47, shared photos of her look on Instagram with the caption “bite me.”

Her dress — a ’90s design from lingerie brand Jonquil – was slit high on both sides with sheer lace panels, a plunging neckline and a satin paneled skirt. Villa Amour Vintage has the same style up for gras for $629.

Kardashian added a sheer black duster and scarf on top, and doubled up on cross necklaces, pairing a diamond choker with a longer dark pendant.

Hairstylist Andrew Fitzsimons shared snaps of the glam, writing, “@kourtneykardash minus the bangs for Landon’s vampire bday party 🫦🧛🏻‍♀️🩸🖤.” The reality star’s usual fringe was twisted and pinned back for the occasion.

Landon is Travis Barker’s son with ex-wife Shanna Moakler. At the party, the musician blew out the candles on a black cake spattered with faux-blood glaze.

Kardashian also shared a photo of his second cake, topped with 23 black candles and the words “Nobody likes you when you’re 23,” a nod to his dad’s Blink-182 hit “What’s My Age Again?”

Kardashian has had a soft spot for the undead for years. In 2021, months into her romance with Travis Barker, she debuted diamond-studded crowns on her canines and captioned the selfies with a vampire emoji.

Other guests at the party also got into the theme, with the birthday boy sporting a leather suit sans shirt, sister Alabama Barker sporting a fire-red wig and Alix Earle sporting a busty latex minidress.

Earle’s sister Ashtin, who wore a sheer lace getup at the fête, have been dating for the past weeks.
