It is generally considered inappropriate and disrespectful to speculate about the religious beliefs of public figures, especially when it comes to sensitive topics like sectarianism. While there might be rumors or speculation about certain celebrities' religious affiliations, it's important to respect their privacy and avoid spreading unsubstantiated claims.
Public figures often keep their personal beliefs private, and it is not ethical to make assumptions or judgments about their religious practices.
It's important to foster a culture of respect and understanding, recognizing that everyone has the right to their own beliefs and practices.
