‘AMERICAN Idol” rocker Constantine Maroulis has a past – a past that includes an appearance on the dating showing “Elimidate.”

The makers of the show – where one person dates four people at once, sending three home during the show – are hauling Constantine’s episode out of the vaults and airing it Wednesday night (1:35 a.m., Ch. 2)

In the episode, Constantine dances shirtless, tells the girl he is a singer, that his voice is his “secret weapon” and brags “I know what I’ve got.”

There was no word on when the show was first recorded.

Constantine, a New Yorker, tried out for “Idol” to promote his band, Pray for the Soul of Betty, he told reporters.
