We're told the former in-laws all chatted and exchanged positive words. It wasn't a lengthy meet and greet -- Lamar was on his way out -- but a family source tells us the sisters were happy to see him out and doing well. We're told all 3 feel no bad blood toward Khloe's ex.
It could have been way different if Kim or Khloe were there -- at least based on the major shading that went down earlier this year. Lamar did an interview saying his marriage was over when Khloe moved on to "her second or third NBA player." Kim fired back it was over when he got caught at his "second or third brothel."
No such fireworks, though, from Kylie, Kourt and Kendall. As our source put it, "Everyone has moved on with their lives."
