On Sunday, Katy Perry had the “scariest” night of her life at Knott’s Scary Farm.

The singer went to the Halloween attraction this weekend with a skeleton face painted on, captioning the photo “Be honest with me, do I look tired?” on Twitter.

Perry seems like any other girl visiting a Halloween-themed scare park in October, with her pink hair seeming blond (and muted) and a black and grey striped jumper. Only her makeup seems to have been professionally done. She could simply work part-time as one of those terrifying persons that emerges from behind a tree with a chainsaw and terrorizes diners and customers!

After a night at California theme park Knott’s Berry Farm, the California Gurls singer shared another selfie of herself with pals, who were also costumed.

‘Scariest night of my life! @knottsberryfarm BOO!’ she wrote.

Some fans recognized Katy and her companions, so they weren’t entirely incognito. Randomvince27, a Tumblr user, said on his blog:

“Last night Katy Perry and Russell Brand went on Xcelerator 8] (sic) I got to see them and talk to them, they had their faces painted so they couldn’t be noticed. Katy asked one of my coworkers to make out with her but he didn’t know it was her so he turned it down, my supervisor called him an idiot hahaha.”

Following Cee Lo Green and last year’s sinner Matt Cardle’s performances this week, Katy is scheduled in London this week to sing on Sunday’s X Factor elimination show.

Meanwhile, her spouse, recovering alcoholic Russell Brand, was photographed in west Hollywood at the My 12 Step Store.

The store offers books, medallions, chocolates, and T-shirts to encourage addicts to seek help.

Russell, 36, was clearly showing his support for a recovering buddy by purchasing a greeting card that stated, “One f****** day at a time.”
