Kim Kardashian Sex Tape

It may be the most awesome wedding gift of all time ... Ray J is giving Kim Kardashian and Kanye West a $47K check ... representing 4 months of his 2014 profits from the epic porn tape with Kim.

It's breathtaking on 2 levels -- that Ray J has such humongous cajones, and that the tape is still raking in a fortune after 7 years.

Here's the breakdown of the wedding gift. Mind you, this is just Ray J's cut:

-- January $6,135.60
-- February $20,097.31
-- March $9,674.76
-- April $10,931.52
-- TOTAL: $46,840.13

Now get this ... sources from Vivid Entertainment tell us the tape has grossed $50 MILLION!

Remember, we're told Kim gets AT LEAST as much as Ray J, though we don't know exactly how much.

We've reached out to Kim to see if she'll accept Ray's gift, but so far no word back. We're told ... if she doesn't want it he'll donate the money to her favorite charity.

Ray J -- yes, that's his wallet AND he's happy to see you.

Kanye West decided it's finally time to destroy Ray J -- and last night he blasted his lady's sex tape partner on national TV ... going straight after Ray's manhood.

West made a surprise appearance on "Late Night with Jimmy Fallon" to perform his hit "Bound 2" -- but during the song, he changed some of the lyrics to attack Ray:

"Brandy’s little sister lame man he know it now ... When a real brother hold you down, you ‘sposed to drown."

We're guessing Kanye is finally responding to Ray's song, "I Hit It First" ... in which Ray bragged about bangin' Kim Kardashian before Kanye did.

But the best part of Kanye's attack ... the legendary Charlie Wilson punctuating the venomous lyrics with a "shabadabatweeetweeetweee"

It's awesome.

Depending on your standards these may or may not be the most awesome pics you see today -- photographic proof Kris Humphries' sloppy seconds Myla Sinanaj shot a hardcore porno.

TMZ broke the story ... Myla believes her sex tape will make her the next Kim Kardashian -- telling us, "I may not like Kim, but she was smart and she's sexy and I look a lot like her so why not make a tape and make millions and get a reality show?"

Myla even screened Kim K's famous sex tape on a TV while she got railed on camera.

Oh the humanity! The unedited master of Kim Kardashian's sex tape -- Kim K Superstar -- almost burned up over the weekend in a raging fire at Vivid Entertainment ... TMZ has learned.

The master -- think of it as the Mona Lisa of sex tapes -- was secured in a safe inside Vivid honcho Steve Hirsch's office. When the blaze erupted Saturday night ... Hirsch was miles away at an L.A. Clippers game.

Hirsch got the 911 call and bailed immediately, because the safe not only contains Kim's tape but every unedited master of every celebrity sex tape in Vivid's stable, including the ones starring Kendra Wilkinson, Pam and Tommy Lee, Jimi Hendrix, Vince Neil, Tom Sizemore, and Chyna.

Also in the vault -- several celebrity sex tapes that have never seen the light of day.

Fear not ... because Hirsch made it just in the nick of time. The safe was singed but the contents were intact.

Kim Kardashian's sex tape sales have exploded since Kanye West told the world they're expecting ... TMZ has learned.

We spoke to the folks at Vivid Entertaintment -- which owns 'Kim K. Superstar' -- and discovered lots of Kim's fans are celebrating the baby with umm ... visual aids.

Vivid says video-on-demand purchases of the sex tape have spiked 80% since Sunday night ... the fattest increase they've seen since Kim's wedding to Kris Humphries.

Further, Kanye's been boosting biz for months now. We're told overall sales of Kim's sex tape -- be it VOD, online, or DVD -- have steadily increased every month since he and Kim hooked up last Spring.

So, the real winner in the whole Kimye baby hysteria -- Ray J!

There is NO new Kim Kardashian sex tape being shopped around the porn community -- in fact, a XXX sequel doesn't even exist ... this according to Vivid Entertainment.

Of course, Vivid would know ... besides being the biggest name in porn, it also owns the copyright to the original Kim K sex tape.

Now, Vivid honcho Steve Hirsch tells us ... the company has been investigating the rumors of a 2nd tape ... and has determined that it's total BS.

"We’ve already spoken to the third party that brought the first tape to us," Hirsch says ... "and, a second tape, or additional footage from the first tape isn't being shopped around or even exists."

Before Kanye West was nailin' Kim Kardashian ... he used to nail other chicks while watching Ray J nail Kim Kardashian.

Multiple sources with first-hand knowledge of the situation tell us ... Kanye used the Kim K sex tape in the bedroom to get him in the mood ... and it always worked.

As we previously reported, Kanye has had a thing for Kim dating back several years ... and even tried to get her to break up with Reggie Bush in 2009 so they could get together.

We know he loves the sex tape ... he even raps about it on his upcoming album.
