Katy Perry is getting into Halloween early!

The "Last Friday Night" singer loves her costumes -- both on stage and off -- so it should be no surprise that she went all out for a trip to Knott's Berry Farm in Buena Park, Calif., on Sunday.

Keeping in theme with the amusement park's Scary Farm, Katy painted a very detailed skeleton over her face and neck. "Be honest with me, do I look tired?" she Tweeted with the pic above.
