As Heidi Klum could've warned her fellow supermodel — when it comes to fashion, one day you're in, the next day you're out. 

Page Six says Elle Macpherson is out as host of NBC's design show Fashion Star, although she will stay with the show as an executive producer.

The format of the series may also change when it returns for Season 2. Judges Jessica Simpson, John Varvatos and Nicole Richie are all reportedly returning, but co-sponsor H&M will not be back and producers are considering the idea of not having a host at all. 

What do you think? Will you miss Elle as host? Do they really need a host? Should they change the judges?
