Kim Kardashian made a rare social media appearance posing in a photo with Cameron Sterling and husband Kanye West at a Yeezy show in Los Angles on Wednesday.

Sterling is the eldest son of Alton Sterling, a black man who was shot multiple times and killed by police outside of a convenience store in Baton Rouge, Louisiana, in July. He attended the concert to celebrate his 16th birthday.

“Shoutout to [Kanye West] & [Kim Kardashian] for showing 16th bday love last night to my client #CameronSterling, eldest son of #AltonSterling,” the Sterling family’s attorney, Justin Bamberg, captioned a photo posted to Twitter.

Kardashian has largely retreated from public life in the weeks since she was robbed at gunpoint in Paris, taking some “much-needed time off,” according to a note posted on her website. While she’s attended a handful of West’s shows, this appears to be the first new photo she’s posed for since the incident.

In response to Sterling’s death ― as well as the killing of another black man, Philando Castile, by police the following day ― Kardashian penned a brief letter titled “#BlackLivesMatter” on her personal website to memorialize the men and reflect on raising a black son of her own.

“This week we watched Alton Sterling and Philando Castile, two innocent black men, get senselessly murdered by police officers,” Kardashian wrote in July. “Like a lot of you guys, I watched the videos, and was appalled and completely heartbroken. I was left speechless, angry and numb.”

“I want my children to grow up knowing that their lives matter,” she continued. “I do not ever want to have to teach my son to be scared of the police, or tell him that he has to watch his back because the people we are told to trust ― the people who ‘protect and serve’ ― may not be protecting and serving him because of the color of his skin.”
