Estella's last name is Gardinier. It's been in the media several times but she has yet to do an interview. Probably because she lives in LA and if they did an interview with every reality TV contestant they wouldn't have a newspaper big enough.
The other girls are all from other towns around the country where being a reality tv contestant is actually somewhat unique, and their local paper has done a short feature on them.
Somehow I don't think the LA Times has been beating down Estella's door.
