Kanye West is bonding with Nori as the rapper did a rare father-daughter outing Saturday to see Captain Underpants!

Kanye cuddled his little girl on their way into the theater and held her hand as they walked through the lobby. But there were moments when Yeezy wasn't so focused on his daughter and seemed to drift, according to our photographer on the scene: "Kanye spaces out -- he just smiles at Nori and then looks empty, like he's just going through the motions. He doesn't seem to have much energy and he looks like he's just going where the bodyguards tell him to go."

So what gives? Maybe Ye is nervous about having a third child? Maybe he's still recovering from her breakdown last year ... Or maybe he's in shock over news is step sister-in-law Kylie Jenner is pregnant!!!
