Keyshia Cole no longer backs the Donda Academy.
The singer recently withdrew her son from Kanye West's private school.
The mother-of-two lost faith in the academy's founder.
Cole's decision came after West tweeted about shooting up a school.
This threat came after the rapper's antisemitic remarks.
West's empire has crumbled because of his controversial statements.
The Hip-hop star previously announced the closure of his school.
However, the rapper retracted his statement and reopened the school.
Nonetheless, West has lost significant members of his educational team.
