. She shared a photo of herself seemingly engrossed in the children's book before a gig on July 28.

and almost called @abiander to talk about how scary sharks are," she Tweeted
on Tuesday. "Then got this overwhelming fear that they can hear me."
Maybe the Cuddly Kittens
sequel Playful Puppies
would take her mind of things?
