I have never read any Статья about their friendship. But I think that for sure they were in very good relations. They were meeting each other on different kind of parties, took pictures together, I think they weren't so close like Алия with Missy или Timbaland, but I know that they admired each other and respect too.
On the picture Ты see that nobody pushed them to take this photo, they really like each other, and I'm sending also a video where Lisa talks about Aaliyah...
