We missed her cameo. Her character's name was "Angela," if that helps to I.D. her in any way.
Re your spoiler question, the Wikipedia page for Enchanted has this info, though personally I have no recollection of it:
Spoiler:
The soap opera shown on the television is a tribute to Beauty and the Beast: it stars Paige O'Hara, Belle's voice in Beauty and the Beast. The character she plays on the soap is named Angela, a tribute to Angela Lansbury. The other actor on the soap opera is named Jerry, a tribute to Jerry Orbach. The actors mention a third character named Ogden, a tribute to David Ogden Stiers. The background music for the show is the song Beauty and the Beast, and the set design is based on that film's bandaging scene.
