Warner is survived by his wife and daughter, the latter of whom was born in 2017. While notoriously private, he has, however, posted about both his other half and their child on social media.

He and Eddie Griffin led the sitcom Malcolm & Eddie from 1996 to 2000, and Warner was also well known for his role as Alex Reed on Reed Between the Lines, which he starred in alongside Tracee Ellis Ross from 2011 to 2015.
