Inside Kim Kardashian’s wild 45th birthday! Scantily-clad star parties up a storm with Kate Moss before kissing topless model at star-studded bash

Kim Kardashian had a fun-filled 45th birthday celebration at photographer Mert Alas’ home in London on Wednesday.

And in new exclusive shots, the superstar can be seen partying up a storm with supermodel Kate Moss before kissing a topless model.

Kim looked incredible as she posed up a storm with stars including Kate, Stella Maxwell, Naomi Watts and FKA twigs during the star-studded event.

The mother of four wore a sheer corset top as she headed to the party with her mother Kris Jenner and fashion designer John Galliano.

Throughout the night, fashion designer and socialite Daphne Guinness sang without warning before musician Cyrill Ibrahim took to the piano.

Meanwhile, no one could stay silent as Seventy-One’s Golden Martinis flowed, the night filled with candlelight, music and London’s most creative artists gathering for the kind of post-midnight decadence only found behind the closed doors of Mr. Alas.

During the star-studded event in the capital, Kim was seen kissing a topless performer wearing a jeweled thong and feathered headpiece.

The former showed off her hourglass figure as she wore a cleavage-enhancing sheer corset and thigh-skimming silk skirt.

The latter wore a fitted minidress made of more sheer material, as well as a revealing bralette piece at the top.

Dazzling bead details were embroidered throughout the outfit, which also included tassel decorations.

Kim has known fashion photographer Mert Alas for many years and has worked with other celebrities, notably Ariana Grande, Demi Moore and Kate.

Before attending Wednesday’s bash, Kim also embraced her edgy side at the London premiere of All’s Fair in Leicester Square.

The American Horror Story: Slender star wore a black snakeskin dress that clung to her body and also wore a black veil that covered her arms.

She wore a pair of black heeled boots and added several silver chain necklaces to complete her outfit.

Kim has been busy and also celebrated her birthday in Paris earlier this week, which started with her attending the premiere of her upcoming new series.

For the special event, she wore a figure-hugging blue dress with a low-cut front and was supported by her mother, Kris Jenner.

Kim later blew out the candles on a lavish cake with her All’s Fair castmates in a video shared on social media.

The star then made an outfit change later in the evening, sporting stunning looks from Alexander McQueen and Givenchy.

He was seen leaving his hotel in Paris before heading to iconic cabaret venue Crazy Horse to continue his birthday celebration.
