Ciara Drops Libel Case Against Future

Ciara has a legal problem that actually serves her well ... she can't win her defamation lawsuit against baby daddy Future because she's raking in so much money professionally, she has no damages.

Ciara's lawyer, Larry Stein, just filed legal docs dismissing the remaining libel claim she filed after her ex said some choice things about her, including, "This bitch got control problems."

Problem is ... to win a defamation lawsuit, you have to prove you've suffered financially, and Ciara is actually making more money now than before Future talked smack on her.

So she's dropped the libel claim -- the judge already dismissed a separate defamation claim -- but the case isn't over.

Russell Wilson's wife is still suing Future for what's called "false light" ... alleging Future has made her look like someone she's not. Proving false light does not require a showing she's lost income. She could get money just for the heartache of it all.

So the case goes on.
