EXCLUSIVE: "Idol" Adam Lambert As You've Never Seen Him

Here's American Idol finalist Adam Lambert as you've never seen him before.

RadarOnline.com obtained this exclusive photo of Adam before he went glam, when he was starring as an all-American football jock in the Lake Tahoe production of the "naughty" musical Debbie Loves Dallas.

The photo is from 2006.

Suzi Slye Elasik, pictured with Adam, was at the show and is now rooting for him on Idol. She told RadarOnline.com: "Adam played the lead in the play opposite Debbie. He was wonderful in it - he sang, he danced and his stage presence was amazing. Adam was so clean cut, polite and a gentleman - the son every mother would love. He was friendly, humble, gentle and snuggly. I was so smitten, being a grandma that he hugged me and was so nice."

The musical, which received rave reviews, is not associated with the infamous adult X-rated film Debbie Does Dallas. The play does have some topless scenes and was touted as "Tahoe's hottest sexy adult revue." It played at Harveys Lake Tahoe Casino and Resort to an over 21 crowd only.

Ironically, this production was directed and choreographed by Jennifer Lopez's ex husband Cris Judd. 

Suzi, an "American Idol" fan, is certainly rooting for Adam.

"Are you kidding me?" she told RadarOnline.com.  "I knew him before he was famous so I'll definitely be watching tonight and cheering on Adam!"
