Keeping up appearances is hard to do when you're Jersey Shore's Snooki.

After a rough night of partying with roommates J-Woww and Deena Cortese on Thursday's all-new episode, the pint-sized Snooki takes a break -- hiding in a bush outside the nightclub.

"We're laughing and having a good time, and all of a sudden, Nicole takes off," J-Woww says of her pal in an exclusive preview from the episode.

Later, Snooki is puzzled by her own bizarre behavior.

"Honestly, who hides in a bush? Only me. I will pee in a bush, poop in a bush, hide in a bush," she reasons. "I do f--ked up s--t. I don't know what's wrong with me."
