When Moby recently told Spinner that Britney Spears and Ke$ha don't make "music" but rather "advertising for ringtones," no one came to the pop stars' defense. But now the original pop princess, Debbie Gibson, tells me Moby should zip it and stop taking himself so seriously.

"He should pick on someone his own size," Debbie tells me, joking about the diminutive Moby. "First of all, for any artist to slam any artist, I think is wrong, because art is subjective, you know? I can look at a painting and think it's the most beautiful thing and someone else can go, 'It looks like a 3-year-old made that!'"
