Robson had denied being molested by the late singer in Jackson's infamous 2005 child molestation trial but in a recent about turn, the choreographer filed a lawsuit against Jackson's estate, alleging Jackson sexually abused him for 7 years as a child in 1990.
Robson, 30, has filed an amended complaint where he claims that the alarm would go off whenever someone came within 30 feet of Michael Jackson's room. Robson claims Jackson also hung a "Do Not Disturb" sign on his bedroom door, TMZ reported.
In the lawsuit, Robson claims he and Michael Jackson frequently shared a bed, the late singer often showed him porn, he told Robson they loved each other but no one would understand and he needed to keep his mouth shut.
The choreographer claims he testified in favour of Jackson in 2005 because the singer had brainwashed him. Jackson's estate has rubbished Robson's claims as "outrageous" and an attempt to get money out of late singer's estate.
