RAY J is reportedly giving KIM KARDASHIAN and KANYE WEST $47,000 as a wedding gift.  Although they probably won't accept it . . . because it's Ray's cut of four months' worth of profits from the SEX TAPE he and Kim made.


Yes, that porno is the gift that KEEPS ON GIVING.  Ray banked a little over $6,000 in January, about $20,000 in February, around $10,000 in March and close to $11,000 in April.


Let's not forget, the tape is SEVEN YEARS OLD now, and it's still paying off.  Kim makes AT LEAST as much as Ray off the tape, maybe even MORE, since they probably had to negotiate harder for her consent.


Vivid Entertainment says the movie has grossed $50 MILLION to date.
