Debbie Gibson was a pop princess of the 1980s.  She was also a spokesperson for Natural Wonder, Revlon’s more youthful brand (since discontinued).

Debbie Gibson’s “rival” was Tiffany Darwish, whose stage name was simply Tiffany.  Tiffany became a spokesperson for a rival brand: was it Maxi by Max Factor or Maybelline’s Shine Free?  A Google search hasn’t turned up anything.  Please help – I would like a picture to pin to The Style Page | beauty | vintage board on Pinterest.
