In a recent interview with AOL Television to promote the return of his A&E reality show “Gene Simmons Family Jewels,” Gene said Adam’s decision to come out has effectively stopped the handsome 20-something’s career in its tracks.

“He’s enormously talented, best talent ‘American Idol’ has had, but I think he killed his career because now conversation is not about his talent but about his sexual preference,” Gene said.

Shortly after “Idol” wrapped up, Adam came out in a cover story for Rolling Stone magazine — although, by his own admission, Adam joked he was “never really in” the closet. But Gene believes some people won’t be able to get past Adam’s revelation about his sexual preference.
