(LOS ANGELES) -- The FBI is investigating a suspicious letter sent to Khloe Kardashian Odom at the CBS Studio set in Los Angeles where the Fox singing competition The X Factor is staged, according to TMZ.com.
The letter, received by the studio on Tuesday, contained a white powder that was ultimately deemed harmless. The contents of the letter itself are unknown.
Kardashian Odom, who made her debut as a new X Factor co-host earlier this month, vaguely tweeted Tuesday afternoon, "Awkward."
The same complex received similar suspicious packages during both of Bristol Palin's stints on ABC's Dancing with the Stars, which is also produced there.
