Kardashian wore an all-black Balenciaga outfit, which included a long-sleeved top, tight pants, over-the-knee boots, and a full face mask. The star also wore black stilettos, with her hair in a long braid.

West presented a new rendition of his album at Thursday’s listening event, per People. Kardashian also posted an Instagram video of the event. She and her children had previously attended West’s first Donda listening party last month, where she wore a red Rick Owens jumpsuit and matching boots featuring bejewelled heels. West also coordinated with his estranged wife in an all-red outfit that night.

The Keeping Up with the Kardashians star filed for divorce from West in February after six years of marriage. The pair have reportedly established a “healthy” co-parenting relationship. A source close to Kardashian told E! News, “Kim wants the kids to stay connected to Kanye and will make that happen. It’s very important to her that she has a healthy co-parenting relationship with Kanye and that the kids have strong relationships with both of their parents.”
