Nicole Richie
Nicole Richie originally rose to prominence on Fox's reality show The Simple Life, where she co-starred with her best childhood friend, a particular socialite, Paris Hilton. These two rich heiresses have gone on to build a name for themselves as fashion icons and divas, so it's odd to see Richie with her guard down – but, to be honest, she doesn't seem any worse for it!
Lea Michele
Leah Michele has been acting since she was nine years old, first appearing on Broadway in Les Misérables – but it wasn't until 2009, when she was 23, that she became an international sensation thanks to her role on the Fox series Glee as Rachel Berry, the show's female lead and star singer – a role that earned her three Grammy Award nominations, w an Emmy Award nomination, and two Golden Globe award nominations. Since then, the gifted actress and singer has appeared in several roles and released several albums, and it appears that she has no plans to slow down – whether she's dressed up on the red carpet or sweating on the hiking route!
