EXCLUSIVEDebbie Rowe doesn't believe for one minute that her ex-husband, Michael Jackson, molested Wade Robson, telling TMZ the latest accuser will not blemish the memory of MJ.
Rowe -- reacting to Robson's appearance on "Today" and the 2 legal claims he's filed in court, tells TMZ:
"I was angered that Wade Robson reversed his sworn testimony from court in 2005, and now claims to be a victim of sexual abuse."
Rowe goes on ... "His publicity-seeking attempt is opportunistic and just oozes falseness."
Robson claims Jackson molested him for 7 years -- between the ages of 7 and 14, although he squarely denied it when he took the stand as Jackson's star witness in the 2005 molestation trial.
Rowe tells us, "It will be quickly forgotten, and will do nothing, nothing to tarnish Michael's extraordinary legacy."
