Mathew Knowles, who is dad to Beyoncé and Solange, reacted to Kanye West’s offensive comments about his grandkids Rumi and Sir, two days after his ex-wife Tina Knowles addressed the posts.

West has been in a spat with his ex over the use of their daughter North West’s vocals in his latest song, which features accused sex trafficker Sean “Diddy” Combs. On Tuesday, he accused Kardashian of controlling their four “BLACK CHILDREN,” adding, “THE MAN HAS THE FIRST AND FINAL SAY OVER HIS KIDS.”
