Don't judge a face by its cover! Kelly Osbourne had a terrifying wake up call on April 22 when she tried to wind down her evening with a soothing facial treatment.

"I was trying to relax and go to bed for my 2am call time tomorrow with a relaxing mask.... But I look more like #HannibalLector! Scared myself out of sleep!" the Fashion Police cohost, 29, captioned a picture of herself wearing a sheet mask on Instagram.

Apparently the reality star still managed to get some shut eye because she later Instagrammed a shot of herself in the car wearing sunglasses while holding her dog. 

"Driving to the next work destination and all we are seeing is people leaving the bars! At least I have Sid with me!" she wrote beneath the pic.
