Photos: Kim Kardashian reunites with estranged husband Kanye West

Kim Kardashian and her estranged husband Kanye West reportedly reunited this past weekend as they visited a museum in San Francisco with their four children.

Kim, 40, and Kanye, 44, visited before opening hours the teamLab: Continuity exhibition at the Asian Art Museum with their children North, eight, Saint, five, Chicago, three, and Psalm, two, on July 17, a museum source told E!. 

'They were excited to be there, and everyone seemed to be getting along great between Kim and Kanye,' the source said. 'They were there for the kids as the museum is a very family friendly environment, and this specific exhibit brings out the childlike wonder in us all. By all accounts they were gracious, appreciative, and had a great time!' 

The famous exes were 'very low key' as they went about the museum. 

The family of four explored the museum with their security guards keeping an eye on them. 

Their nannies, however, did not join them.
