Whether they loved it or hated it, everyone seems to have an opinion about American Idol 8‘s finale.

Even though he fully believes Adam Lambert will have a brighter career than Kris Allen, Gene Simmons doesn’t necessarily agree with the contestant’s musical leanings. The KISS bassist - who performed with Adam during the recent finale - told fans that he doesn’t see rock n’ roll in Lambert’s future.

“Respectfully, I don’t think Adam is a rock singer,” Simmons wrote on his website. “He sounds much more convincing singing ballads and Broadway shows. His voice doesn’t seem to have a ‘rock quality.’ But, I’m sure he’s going to do just fine.”

Hmmm, Broadway? Maybe Lambert has more in common with Clay Aiken than the Season 2 contestant would like to admit!
