WTF?! JACKO SAID HE HAD "NO KNOWN HEALTH PROBLEMS?!

Contract signed by King of Pop for "This is IT" concerts implicitly states he had NO known health problems.

RadarOnline.com has obtained the blockbuster docs  from LA County Superior Court as part of the ongoing estate case and the contract clearly states "Artistco (a company owned by Michael Jackson), hereby represents and warrants that Artist DOES NOT POSSESS ANY KNOWN HEALTH CONDITIONS, injuries OR ailments that would reasonably be expected to interfere with Artist's first class performance at each of the Shows during the term."

Jacko inked the contract personally with his very own-large -than-life signature.

The fact that Jackson underwent a physical with the underwriter unleashes another mystery in the ongoing criminal investigation into his death June 25th.
