Despite their differences, there’s one thing that always brings the Kardashian family back together: product promotion.

Rob Kardashian threw up a rare photo on his Instagram account to support his sister Kylie’s new business venture. The youngest Jenner’s makeup line called Kylie’s Lip Kit sold out in a matter of minutes, when it was released last month, and it looks like family connections weren’t enough to score Rob a shade of Dolce K.

“I guess someone is disappointed they didn’t get Kylie’s lipkit!!!! Don’t worry buddy more coming soon,” he wrote under a photo of his adorable bulldog Chapo surfing the brand’s website.

Rob, who deserves a medal for how little he shares on social media (29 Instagrams in total) also posted in support of sister Khloe’s book “Strong Looks Better Naked” when it was released last month.

After Rob was mysteriously absent from the Thanksgiving family photo seen round the world, momager Kris Jenner set the record straight on her son’s turkey day whereabouts and gave us an update on how he’s doing since he dropped out of the limelight.

“[Rob] lives with Khloe,” she explained on Maria Menounos’ Sirius XM show. “So he was around, and then went over to a buddy’s house. He’s doing all right. You know, he’s doing his best. He’s not into being on camera as much as the rest of us. But he’s working on himself. He’s going to be OK.”

Maybe at the next family function Rob can ask Kylie to sneak a lip kit or two under the table for Chapo.
