Commercial spokeswoman from late 1990's

Occasionally someone will appear in a national TV commercial, and that person will become as popular (or more) than the product they are pitching. A good example of this is Sabine Ehrenfeld from the Overstock.com commercials. Being an attractive woman certainly helped, and it was not unusual for people to inquire about her enough that she even had information about her on the Overstock.com website.

I am trying to identify another spokeswoman that appeared in TV commercials back in the 1998-1999 time frame. She also became popular enough that the company she did the commercial for had a webpage about her. I am trying to find out who she was, but have not been able to Google up anything based on what little I remember.

The lady was quite attractive, and if I remember correctly, probably early 30’s, short dark hair, possibly red. I remember the commercials being for AT&T, but a friend thinks it was AOL. Her first name was Greta?

Anybody remember this lovely lady?

Clara Peller was one serious GGILF!
