Nicole Richie looked shockingly thin at the QVC's "Red Carpet Style - Live from L.A." event at the Four Seasons Hotel in Los Angeles, Calif., on Friday.
The reality star wore a black dress that wrapped around her neck and bared her shoulders, which looked very bony.
An insider recently told Yahoo! that Richie, 32, has been shedding weight by following a juice cleanse diet in which she doesn't eat solid food.
It's reported that she drinks six green juices over the course of the day, both for health reasons and to lose weight.
