There's usually no rhyme or reason to the people that corporate Twitter accounts follow on the social media website.

But fans of the fast food chain has discovered that there is a very good explanation for why KFC only follows 11 people on Twitter.

The people it follows are five former Spice Girls and six men named Herb - because the chain's famous Original Recipe is made up of 11 'spices and herbs'.

The official KFC Twitter account only follows 11 people: the five former Spice Girls and six men named Herb

User Edge on Twitter was one of the first to point out that the account only follows 11 'spices and herbs' though a Reddit user also posted the revelation at around the same time

The revelation has blown fans' minds.

It was first brought to attention on Reddit and Twitter by some eagle-eyed social media users.

Some have even suggested that it might represent the different ratio of spices and herbs that KFC uses in its chicken marinade: five spices, and six herbs.

The KFC Original Recipe is famously made up of a secret combination of 11 herbs and spices

The KFC Original Recipe is a closely guarded secret supposedly kept in a safe that is so well kept that only a few lucky individuals at the company know about it.

It was supposedly revealed to the public last year after a nephew of KFC's founder, Colonel Sanders, found a recipe for the mix in an old scrapbook belonging to the Colonel's second wife.

The 11 herbs and spices are reportedly salt, white pepper, thyme, basil, oregano, celery salt, black pepper, mustard, paprika, garlic salt, and ground ginger, according to the scrapbook.
