Kevin Bacon has apologised to fans after publishing a spoiler for his hit U.S. Tv show The Following online.

The Footloose star, who plays Federal Bureau of Investigation (Fbi) agent Ryan Hardy in the new thriller, risked the wrath of the show's devotees by re-posting a Twitter.com comment which gave away a key plot twist, making it instantly visible to his 233,544 followers.

The episode in question aired in the U.S. on Monday (08Apr13), but had not been shown abroad, and Bacon was quick to apologise for his error, uploading a video of himself repeating the phrase "my bad" three times.

In a post on his official page, he writes, "To all the fans abroad and late watchers I'm truly sorry I retweeted a spoiler. I just wasn't thinking. Won't happen again. (My bad)."
