Here's why it's hard to say for sure:
* Public personas: Musicians often maintain a professional distance and don't reveal intimate details about their personal relationships.
* Limited information: There's not a lot of publicly available information about their personal lives beyond their music careers.
* Changing dynamics: Even if they were close friends in the past, their relationship could have evolved over time.
It's possible they have a strong friendship, but without more information, it's impossible to say for certain.
