They werent a likable band with the original three, they would all refuse to speak in interviews and reveal much, so when Heidi joined she was more prominent in interviews. The original three were complete munters too and sex sells, Heidi made the others up their game with their looks because she is good looking herself. They were either close to being dropped or they were dropped in their original line up, but when Heidi joined she added a new dimension to the band and made them more accessible as well as coinciding with a new sound that probably wouldn't have worked with the original line up.
