Tina Knowles pushed back on Wednesday against the latest deranged ramblings of musician Kanye West, who took time out of a series of offensive and Nazi-themed social media tirades this week to target her two seven-year-old grandchildren. On Tuesday, West asked on social media if “anyone ever seen” the two youngest children of Knowles' daughter Beyoncé, twins she shares with her husband, the rapper and former West collaborator Jay-Z. He then used disparaging language to question their mental capacity. On Wednesday, Knowles, 71, responded with not-so-subtle jab at West, who earlier this week posted an image of himself wearing a swastika chain while posing with white supremacist livestreamer Nick Fuentes. “So I’m on the set of a photoshoot today for my book, and I wanted to tell you a corny joke,” she said, in a video posted to Instagram. “What happens when a snowman throws a tantrum? He has a meltdown. Y’all know that’s funny.” She originally included a caption on her post, reviewed by TMZ, stating it was “hard to remain positive and classy in the face of ignorance and evil,” adding: “I know that no weapon formed against me or my family shall prosper.” Amid West’s increasingly concerning behavior, TMZ reported Tuesday that his ex-wife Kim Kardashian is mulling whether to ask a judge to strip him of joint legal custody of their four children.
