1. KATY PERRY’s roots are showing.

Her “preacher’s kid” roots, that is.

This week, the long-time-ago gospel singer (and daughter of two Protestant pastors) took a break from her vocation as a human cartoon and tried to get serious – with explosive results.

Following the most recent terrorist attack on Israel, Perry tweeted, “My prayers are for you guys tonight, SHALOM!!! #prayforisrael.”

In minutes, supporters of Oz Narnia Palestine were tweeting less than peaceful responses like, “GO to Hell with ISRAEL B**ch” and “I hope your private jet crash lands into Palestine so they can stamp on you like the whore you are.”

Perry back-peddled a bit, pleading neutrality – which then led hundreds of pro-Israel commenters to condemn her as a coward.

At this juncture, it’s helpful to recall that the fellow who once poignantly asked, “Why can’t we all just get along?” is an alcoholic career criminal who ran over his wife with a car.
