Leonardo DiCaprio -- Wins 'I Knocked Up Rihanna' Lawsuit

Leonardo DiCaprio fought the French and won ... but all he has to show for it is a few grand.

The "Titanic" star was awarded $9,000 in damages from the French magazine, Oops! Leo filed suit a few months back over a cover story alleging he got Rihanna pregnant, and didn't want the baby.

Frederic Truskolaski, owner of the mag, expected to lose the lawsuit ... but was anything but magnanimous in defeat, trashing Leo and making more claims that could make him another $9k lighter.

Gossip Cop first reported Leo's win.
