Rob Kardashian made a rare appearance at Kris Jenner's 67th birthday.
The 35-year-old was spotted in a black and white family snap posted on his sister Kim's Instagram.
Rob made the decision not to appear in The Kardashians on Hulu because he didn't want his daughter to be involved in the programme.
An insider told E! in November last year that "everyone respects his decision".
The SKIMS founder proudly stood with Rob, their mum, Kourtney, Khloe and her grandmother Mary Jo "MJ" Campbell for the photo opportunity.
Later on, Kris's daughters dressed up in various outfits and even wore wigs in an effort to look as much like their mum as possible.
In Kim's stories, she shared a video of her wearing a green sequinned gown with a shirt collar and bow.
Her long blonde hair was hidden under a dark brown wig cut into Kris's famous pixie cut.
"Ok so it's my mum's birthday dinner and it was Dress Up As Your Best Kris. Does this one look familiar, guys?
Popping one hand on her hip, she continued: "Her Christmas card from 10 years ago, and we did that music video in it."
She then added the clip from the video of Kris lip syncing to Lady Marmalade by Christina Aguilera.
Kylie and Khloe both pulled out the stops on their outfits, with Khloe wearing a platinum blonde wig.
She wore a white silk gown with red roses across it, with bright stilettos in the same colour.
Kylie, who wore a black sequinned gown with spaghetti straps, was Kris in 1989.
Kourtney wore a pink tracksuit, trainers and Kim said she was the "thank you, next Kris Jenner".
She turned to the camera and held onto a video camera that looked as if it were fresh out of the nineties.
Kim captioned the selection of snaps "Happy Birthday mommy @krisjenner. We had so much fun last night celebrating you," Kim captioned the post, "and loved feeling what it's like to be a version of you dressing up like you. It felt powerful and fun! That's who you are!"
The famous family posed around a white frosted cake with a heart placed on top.

Kris waved her hands with glee as she blew out the candles.
Sharing details from the day, Kim wrote: "Hearing all of your friends give speeches about how no matter what you make the time and show up for each and every one of them made me happy they got a glimpse of what it’s like to be your daughter.
"No matter what you show up for me and all my siblings at any hour of the day and never ever complain when we all need your attention at the same time," she added.
The businesswoman ended her tribute with: "Thank you for being the best teacher and I only hope I am half the mom you are because you are the absolute best. I love you so so so much."
