The former NBA star was spotted holding nephew Mason's hand, while Kardashian carried her niece Penelope.
Kardashian, 31, who live-streamed with Odom on their way to the church, wore an all-white outfit complete with large hat, while Odom, 36, was more casually dressed in a gray hoodie and black pants.
It's the second public outing this week for the pair, who stepped out for dinner together in L.A. on Friday.
The Keeping Up With the Kardashians star called off their divorce after Odom was hospitalized in October following an overdose at a legal Nevada brothel. She was a constant presence by his side in the hospital and has been helping him with his rehabilitation since his release.
While she insists that they haven't rekindled their relationship, Kardashian recently revealed on her talk show, Kocktails With Khloé, that she's open to starting over with Odom.
"I mean, that would be, like, the best dream," she said. "Like, OK, I hope that first marriage could happen again, but it’s really hard to erase everything that happened. Just building a friendship back is what I’m doing now. It has nothing intimately, nothing at all, just pure love, and I want someone to learn how to love themselves again.”
