Kanye West Brings JAY Z and Beyonce's Children Into It

Kanye has been sliming everyone lately.  Most of his targets can brush it off.  It's just Kanye, after all

But the slime he just tossed on his old pals JAY-Z and Beyonce might be a bridge too far.

"WAIT HAS ANYONE EVER SEEN JAY Z AND BEYONCE YOUNGER KIDS  THEY'RE RETARDED NO LIKE LITERALLY AND THIS IS WHY ARTIFICIAL INSEMINATION IS SUCH A BLESSING HAVING RETARDED CHILDREN IS A CHOICE," he typed.

JAY-Z and Beyonce's twins, Sir and Rumi, will be eight in June.
