Producers of Fox's "X-Factor" got quite the scare when they received a letter to Khloe Kardashian containing a suspicious white powdery substance. According to TMZ, the letter arrived to CBS studios on Tuesday morning and the police were immediately involved in the situation.
The FBI is reportedly investigating the powder, which was deemed "harmless" by officers called to the scene. There was also a letter written inside the envelope, but it's contents have yet to be released.
Earlier this year two letters were sent to Bristol Palin at the same CBS studio, which also contained a mysterious white powder. In Bristol's case, the white powder turned out to be talcum powder.
It's still unclear whether the two incidents are related.
