Nicole, the reigning queen of April Fools’ pranks, seems to have topped herself with her latest endeavor!

There is some good news for Kardashian fans today, and some bad news. The great news is that Kim and Khloe Kardashian‘s Twitters have been hysterical, albeit inappropriate, all day with tweets detailing lewd sexual encounters, bowel movements and creative uses of the letter “K.” The bad news, it seems to be the hilarious Nicole Richie making these tweets.

Take a peek at just a few of the tamer tweets above and remember, Nicole pulled this same stunt back in 2010! Kourtney has been spared as of now, but she might want to be careful!

So what do you think on Nicole’s tweets — hysterical or horrifying?
