It looks like you’re asking about something one specific “Lisa” said about a specific “Demi,” but there are many well‑known people with those names (for example, Lisa Vanderpump and Demi Engemann, or other public or private figures), and different situations where one might have spoken about the other. Without more context about which Lisa and which Demi you mean, the situation (TV show, workplace, friend group, etc.), or roughly when/where this happened, it isn’t possible to accurately say what was said without risking mixing up the wrong people. To be helpful without guessing, here are a couple of ways you could clarify:

• Identify who you mean (for example, “Lisa Vanderpump and Demi Engemann from reality TV,” or “my coworker Lisa and my friend Demi”).
• Add where or how this came up (a podcast, a show episode, a social media post, or a personal conversation).
• Mention any specific topic (for example, “what did Lisa say about Demi’s allegations” or “about Demi cheating,” “about Demi’s work,” etc.).

If you share a bit more detail, a concise, specific answer about what was said and in what context can be provided.
