With friends like these, who needs enemies? As Wetpaint Entertainment previously reported, the invite to Snooki’s baby shower – set to take place this Sunday, August 12 – was leaked last week to the New York Daily News. Now we’re receiving word that not only was Snooki not behind the leak, she’s furious about it because she thinks a friend did it behind her back.

“Snooki is livid that the invite got leaked to the press,” an insider close to the Jersey Shore star tells Wetpaint Entertainment. “It’s a private event that’s supposed to be for family and close friends. Now the whole world knows about it.”

“She knows there is a big rat in her camp,” the insider continues. “She’s certain that whoever leaked the invite to the media is the same person who first told Star about her pregnancy. She’s disgusted.”

However, Snooki is close to zeroing in on the culprit. “She’s narrowed it down to one or two people and when she finally confronts who did it, it’s not going to be pretty.”

In the meantime, security will be amped up on Sunday to prevent crashers or paparazzi from getting too close. “She’s upset that security will now be a major concern at her shower,” the insider concludes. “But she’s dealing with it.”
