Well the MJ Estate can rest, there is no secret love child.  TMZ reports,

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.
