Debbie Rowe -- Wade Robson's a Publicity-Seeking Opportunist

Debbie 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.
