During Fox Report with Shepard Smith, the host recapped a summary of the story before turning to discuss the incident with a representative of the mining company.
Thinking that he was speaking to a local spokesperson, Smith asked the caller: "What have you learned?"
The prankster then replied: "We have learned that Jamie Foxx is a c**t."
Smith immediately cut the man off before apologising and expressing his irritation at the prank, saying: "It's never happened to us here but it's always distressing when there are six people killed at a mine disaster and we're waiting for 21 others to find out whether they are alive or dead and something like that sneaks by our screeners. Disgusting."
The caller was later reportedly discovered to be a fan of the controversial radio DJ, who has been involved in a running on-air feud with Foxx after implying that the star is secretly gay.
