"I have every single episode of every season of every Star Trek," True Blood/Pacific Rim star Rob Kazinski told VH1 News earlier this summer. "I have every movie. I have original artwork. I have costumes. I'm a big fat guy who loves star trek stuck in ... um, this body." Well, he didn't exactly sound too guilty about his so-called "guilty pleasure," and he's just one of the many celebrities who were eager to reveal their love for literal and figurative junk food.

"The Notebook gets me every time," One Direction's Niall Horan said. "And Marley and Me. The bottom lip goes!"

"Real Housewives," answered Kristen Wiig. "That's everybody's guilty pleasure, but I watch it religiously."

Mark Wahlberg let on that cookies and pasta are his evil treats. "Nothing that's going to upset the tummy; I'm lactose intolerant." Is that how he maintains those Marky Mark abs?
