Fox News host Megyn Kelly made a profane error while introducing Mike Huckabee onto her program Monday night.

"Joining me now, former Arkansas Governor Mike Huckabee, who is the host of F***a—," she said, before noticing her error and immediately correcting it.

Twitter quickly reacted to Kelly's mistake.

Later in her show, Kelly addressed the mistake, admitting that she had in fact "sworn once on the program."

"Something else that happened on the program is also getting a lot of attention on Twitter and including this tweet from some nice man named Sean who said ‘Megyn you’re a delight to watch and gave a stoic performance after your slip up with Governor Huckabee’s name.’ I thought I was stoic too – I have a heart of a 12 year old boy," she said.

This story has been updated to include Kelly's later comments.
