BOW WOW HAS TO PAY FRENCH PORN STAR "KATSUNI" $80K

Bow Wow has to cough up nearly $80,000 to a French porn star .... for allegedly jacking footage of her dancing and splashing it all over one of his videos without her permission.

Adult film star Celine Tran -- known as "Katsuni" -- sued Bow Wow back in July 2012, claiming he stole clips of her pole dancing in a music video for a French band called Electronic Conspiracy and then used a ton of the footage in his music video "Drank in My Cup" ... sans permission.

Bow Wow didn't even respond to the lawsuit, so a federal judge ordered him to pony up $79,346.07 (damages + attorneys' fees) ... and stop with the footage STAT.

Sad part is ... for $80k ... he never got to see her naked or f**k!
