Scott celebrated his big day at trendy restaurant Nobu in Malibu and despite his recent ups and downs, his nearest and dearest turned out in force.
Kourtney, Khloe, Kris, Corey, Kylie and the kids were all spotted making their way into the sushi restaurant dressed in an array of glamorous outfits.
But, when it came to flesh-baring factor, no one could beat reality royalty Kim’s see-through lace look.
The mum-of-two, 35, pulled out all the stops in the daring creation which looked like it was probably more suited to wearing to bed or being used to cover a dining table.
Er, we can see your undies Kim
Khloe was also rocking a fierce J-Lo inspired look
The plunging lace number, which she wore with a matching white choker and nude heels, naturally showed off plenty of bronzed skin and cleavage.

Khloe, who was seen carrying North, was also courting plenty of attention in a fierce J-Lo inspired look made up of tight white jeans, white heels, a white top and a light blue long fur coat.
Finishing off the look, Khloe wore her hair scraped back into two high ponytails and wore a bandana tied around her head.
Kris was all smiles as she was joined by boyfriend Corey Gamble

Birthday boy Scott, who was also lavished with love over social media throughout the day, appeared to be in good spirits as he carried his daughter under one arm as they made their way into the ocean-front venue with the Keeping Up With The Kardashians cameras in tow.
Kourtney, who shared a throwback snap of her straddling her ex earlier in the day as she wished him happy birthday , also went all out of the occasion in a sexy back jacket, shorts and strappy heels.
Despite recent reports she was upset about Scott being so public with his romance with his rumoured new girlfriend in Cannes, Kourtney was sporting a huge grin.
