Radar is told The Keeping Up With The Kardashians star and her estranged husband's team worked with the Asian Art Museum in San Francisco to ensure the former couple's "privacy."
We spoke with Zac Rose, the associate communications director for the museum, who revealed, "We opened a little early for them, to avoid a spectacle, and give them some independence and privacy."
Radar is told the famous exes brought their four children -- North, 8, Saint, 5, Chicago, 3, and Psalm, 2 -- to see the venue's brand new teamLab: Continuity exhibition, something the rapper was eager to experience.
"Kanye is a fan of teamLab, a Tokyo-based international art collective that uses digital tools to create immersive, dynamic ecosystems that dissolve the boundary between visitor and artwork," Rose tells Radar.
Kim and Kanye "weren’t doing social while they were on site since it was a family visit," he added.
And despite their ongoing $2.1 billion divorce battle, we're told Kimye put their differences aside to co-parent during the weekend tour -- and it went seamlessly.
We're told they were "gracious" and "appreciative" of the museum's effort to keep their reunion under wraps -- and the estranged couple had a "great time" with their kids.
It's an interesting move that Kim and Kanye took their children to SF amid their divorce.
The Jesus Is King rapper famously popped the question at AT&T Park -- now known as Oracle Park -- on Kim's 33rd birthday in 2013.
This wasn't your average stadium proposal on the Megatron either. Kanye hired a 50-piece orchestra to serenade Kim and made sure the KUWTK star's family and friends were on standby for the big surprise.
Hours after joining Kim and the kids in SF, Kanye jetted off to Las Vegas for another super-secret event.
Ye hosted an album release party for a select few in Sin City, and he's rumored to be dropping Donda sometime this week.
