She's the eldest child of one of the most lavish families in the world, so it was no surprise that Kourtney Kardashian celebrated her 40th birthday in style.
The mum-of-three gathered all of her most famous friends for the party of the year, which the Instagram-loving klan documented in full online.
Kourt wowed in a barely-there black leather and mesh Versace dress, which just about kept her modesty covered with some tactfully placed strips of fabric.
Though she didn't post any videos of the party herself, Kourtney appeared to be having the time of her life on the dancefloor and mingling with her guests.
Her incredible birthday cake was a marzipan model of a naked Kourtney sitting on the edge of a bath, which was modelled after a recent nude photoshoot she did .
She even had a solo saxophonist who played Isn't She Lovely especially for her.
Among the celeb guests lucky enough to nab an invitation were Kourt's ex-boyfriend Younes Bendjima, Paris Hilton and Robin Thicke .

The Blurred Lines hitmaker even sang happy birthday to the TV star on the microphone.
Partygoers were given bottles of Don Julio tequila to take home, which they could get engraved with anything they wanted.
One bottle had been personalised with a picture of the birthday girl and the word's "the most interesting to look at", mirroring her sister Kim Kardashian's infamous insult .
Napkins had the words "Kim there are people that are dying" printed on after the famous line Kourt uttered to Kim when she whinged about losing her diamond earring in the ocean.
Kim K wore an incredible vintage Versace dress for the party, which she showed off on Instagram .
The mogul also shared a video of herself dancing with longtime frenemy Paris, who attended the party with her mum Kathy Hilton.
