Michael Jackson's Alleged Son -- DNA Test Results Bogus ... Ripped fr

Here's a shocker -- the DNA test results that allegedly prove 31-year-old Brandon Howard is Michael Jackson's son are BOGUS ... in fact, so bogus ... the logo from the so-called DNA testing lab was ripped from "Terminator Salvation."

As we reported, FilmOn.com's Alki David put on a spectacle Thursday -- claiming he had DNA results proving singer B Howard was the biological son of the King of Pop. He then produced the results showing a "99.99999%" probability that MJ was Brandon's dad.

TMZ obtained a photo of the DNA doc -- allegedly from a testing facility in Ireland called "DNA Lab." We searched high and low but could find no such generic DNA lab in Ireland.

Skeptical, we investigated -- a simple Google image search of "DNA results" turns up a bunch of sample docs with the same exact easily-stealable format as the one we got.

But the coup de grace -- we then Google image searched "DNA logo" and the first result ... literally ... was the same DNA pic used in the "DNA Lab" logo.

And that's not even the best part -- a reverse image search of the logo shows a bunch of results for "Terminator Salvation." A little more digging revealed the logo was used on PROMOTIONAL T-SHIRTS for the movie.

Can't say we're all that shocked.
