ELI5: How come celebrities can't sue the tabloids for libel, when the tabloids print and publish so many false things about them?
gpt
in the US it's notoriously difficult to win a libel lawsuit.  The person suing would need to prove that the statement was false, caused harm to them, and was made without research into the truthfulness of the statement.  If the person is a public figure they also need to be able to prove the statement was made with the intent to do harm or with "reckless disregard" for the truth.

Either the celebrity can't prove the statements are false, they would rather not have to prove it, they won't be able to prove the tabloid didn't research it, or most commonly it'd be hard to prove the lie actually caused harm and the tabloid had "reckless disregard" for the truth.
