Appearing on Good Morning America today, Khloe, 31, spoke about the newest addition to the Kardashian family, who was born in Los Angeles on 5 December.
Khloe gushed: "He is so, so cute. Just a newborn. They don't do much at this age! North is obsessed with him, so that's good. You never know with when they're the only children at first and they get a new on,e you never know how they're going to act.
"North is obsessed with him. North says, 'My name is Saint.' She wants her name to be Saint too. Super cute."
North was born in June 2014.
So far, we haven't seen any pictures of Saint's face or any indication of when the tot will be making his public debut. After North's birth, her famous parents kept her hidden away for a few months before debuting an image of her on Kris Jenner's now-axed TV show.
