Katy Perry
found a good way to go Knott's Scary Farm without being recognized: Face paint!

The singer hit up the Halloween attraction this weekend with a skeleton face painted on, posting the pic on her Twitter with the message "Be honest with me, do I look tired?"

She wasn't the only one in her group in costume, as she was photographed with some zombie friends too.

Sounds like the group had a good time, Katy tweeting after "Scariest night of my life!"
