Both girls were in town for the Art Basel event and posed for pics when they met up inside Miami's LIV nightclub.
According to E! News, the celebrity party pals talked for almost an hour, where they talked about LiLo's recent slim down.
Of course, Kim's daughter North West came up in the conversation, too.
"Lindsay kept saying how much she loved baby North and Kim showed her pics of her on her phone," their source spilled.
Kim also might have shared some swimsuit selfie tips with the young actress, because LiLo later posted a few photos of herself lounging poolside, which is a total Kim K. thing to do!
Do you think Lindsay and Kim are going to keep hanging out?
