Debbie Gibson appears on "Celebrity Apprentice"

NEW YORK -

Debbie Gibson says the one thing she learned from "Celebrity Apprentice" is that the rivalries are not made up. She thought they were a trick of editing or egged on by producers, but she says people snipping at each other is real.

Gibson says when she had cameras on her constantly and was suffering from a lack of sleep, she got snippy too. Isn't she worried that she'll ruin her image? Gibson says she considered that before going on "Apprentice." She called Cyndi Lauper's manager, who said Lauper's ticket sales jumped after appearing on the show.

"Celebrity Apprentice" premieres Sunday on NBC.
