Kim Kardashian is still keeping up with Caitlyn Jenner.
The Kardashians star joined stepbrother Brody Jenner, his fiancée Tia Blanco and their 15-month-old daughter Honey to celebrate the Olympian's 75th birthday on Oct. 28.
"Last night bday dinner in Malibu was so special," Caitlyn wrote on Instagram Oct. 29. "Family is everything! So many kids and so many of the grandkids, all in one place, at one time."
Noting that those pictured in her post were "only a few" out of the numerous people that were in attendance, the I Am Cait alum continued, "You all made my birthday evening so special…and your beyond thoughtful and generous gifts made the night all the more fun (WOW!)!"
She added, "I love you all so much."
One of Caitlyn's photos showed her taking a selfie with Kim, while the two were pictured posing with friends—including Caitlyn's longtime pal and manager Sophia Hutchins—in a group shot.
Kim also shared the selfie on her own Instagram page, writing in the caption Oct. 29, "Happy 75th Birthday. I love you."
Meanwhile, Kourtney Kardashian posted a photo of Caitlyn's birthday cake on her Instagram Stories.
But not every Keeping Up With the Kardashians alum attended the bash. Kylie Jenner, 27, absent from the event because she was in New York for the CFDA Awards that same night.
Another person who was likely a no-show at the bash? Caitlyn's ex-wife Kris Jenner, with whom she shares daughters Kylie and Kendall Jenner, 28.
As the retired athlete pointed out last year, she and Kris—who finalized their divorce in 2014—"never talk to anymore."
"It's sad," Caitlyn told ITV's This Morning, noting that she's "much closer to the Jenner side," which also includes his kids Burt Jenner and Cassandra "Casey" Marino with ex Chrystie Scott, as well as son Brandon Jenner with ex Linda Thompson.
"When you have as many kids as I have, you're closer to some than you are to others," she explained. "And it's kind of that way through there, through that side of the family."
