Michael Jackson’s former public relations adviser has recently claimed that the late pop star sexually abused children and tried to “conceal” it for years.

In a new four-part Channel 4 documentary, Vincent Amen, a former PR agent who worked closely with the musician’s confidante Frank Cascio during 2005 criminal trial, said that he absolutely believes Michael “is guilty of child abuse and molestation”.

Vincent believed that there “was a cover-up for so many years”.

The former PR agent explained how he went from Michael’s defender to “whistleblower” while working insider the late pop singer’s operation.

Michael’s second criminal case, which unfolded in Santa Barbara in 2005, centered on allegations by Gavin Arvizo, then 13, who accused the singer of molestation at Neverland Ranch in California.

Vincent recalled that he was 22 at the time when he joined Michael’s team back in 2003 after the broadcast of Martin Bashir's Living with Michael Jackson.

In the film, the late singer talked about sharing his bed with children, telling Martin, “I have slept in a bed with many children… the most loving thing to do is to share your bed with someone.”

Later, the singer’s comments sparked global outrage and his team came on board to control damage.

However, Vincent disclosed the moment he started believing Michael was actually a culprit after discovering a naturist magazine linked to the singer and Cascio because it features ads for videos for sale, many of which showed “naked kids” that had been “circled to be ordered”.

"Finding that, I realised, 'Something is going on here’… Where there's smoke, there is fire,” he stated.

Reflecting on Vincent’s interview, a source close to the late singer told Radar Online, “What makes Amen's account powerful is that it comes from someone who once helped protect Jackson.”

“His reversal carries weight because it is rooted in what he says he witnessed firsthand,” added the same source.
