That headline is very vague and could refer to many different people. If you want information about a specific actress, please share the actress’s name or the announcement you’re referring to, and I can help summarize or explain it.
If you’re looking for a general article-style rewrite, a more responsible headline would be:
“Fans React After Sad News Is Announced About Beloved Actress”
or
“Beloved Actress: What We Know About the Recent Announcement”
This avoids implying a death or tragedy before the facts are confirmed.
