This is a rumor, but I have heard these two have had a beef with each other for years. Now, it seems, the kids are involved.

The rumor is that Pink reached out and wanted a playdate for her daughter Willow with Gwen's kids and Gwen said nope, not gonna happen, EVER.

Keep in mind, nothing in this story is confirmed, but again, I've heard the rumors about these two for a while so, I'm apt to think they are not, nor will ever be besties.
