Without captioning the post, West, 44, shared a poster that advertised a lineup featuring fellow rappers Future, Quavo and Justin LaBoy.

Earlier this month, a source told PEOPLE that West is still hoping that he and his estranged wife can work things out — even as she takes steps to make their split legally official.

An insider close to the rapper said that family and marriage are "important" to West, and that he's a "family man at heart [whose] love and commitment" to his ex and kids "will never change."

"He's not giving up without a fight. Kim is the mother of his children and he's not going to just let that go," the source said. "No matter if they're husband and wife, they'll always support each other. Her recent filing or any filing for that matter doesn't mean he's going to stop fighting to win her back."

Kardashian, 41, filed for divorce from the Donda rapper in February after nearly seven years of marriage and four children (North, 8, Saint, 6, Chicago, 3 ½, and Psalm, 2½).

The SKIMS founder — who has been dating Davidson since October — previously filed court documents requesting she be declared legally single. Kardashian asked the court to separate issues of child custody and property from her marital status, and also requested that her maiden name be restored.

In the documents, which were obtained by PEOPLE, the Keeping Up with the Kardashians alum said their marriage "has irremediably broken down," and that "there is no possibility of saving the marriage through counseling or other means."
