You don't want to mess with a Mean Girl with a knife!

Actress Amanda Seyfried has plane issues, and her latest was bringing a Swiss Army knife onto a flight. Security should've detected it, which was her point when tweeting a photo of the knife on March 14, writing, "Dear TSA: This Swiss Army knife wasn't detected through security and I unknowingly carried it on board. Scary!"

That is pretty scary, but it's also not her first issue when flying the not-so-friendly skies.

In late February, the New York Daily News dished on Amanda's displeasure when she arrived in L.A. after a flight that week, reportedly saying to the waiting paparazzi, "How the f— did you know I’d be on this flight? I hate American Airlines! They always tip people off on where celebrities are going to be. ... Their customer service is so poor. They don’t even have a greeter for me.”

She later tweeted, “Which airline hires sweaty robot photographers to stalk their passengers? #businessasusual.'" The Daily News quoted an airline rep who said, "As a rule, our employees are not allowed to share any passenger information.” That doesn't meant they don't, but it's also LAX — they probably have paps camped out for celebs at all times.

Anyway, now that Amanda has made it clear she travels with a knife, some of those photographers may want to back off!
