Kevin Bacon left completely baffled after discovering wife is actually his cousin

Kevin Bacon was left completely baffled after discovering wife, Kyra Sedgwick, was actually his cousin.

Back in 2013, the 66-year-old Footloose star and Kya, 59, appeared on an episode of Finding Your Roots, which is kind of like the American answer to the popular British ancestry TV show, Who Do You Think You Are?

Now, the celebrity couple first got engaged back in 1987 and wedded the following year.

They also share two children together: a son, Travis, and a daughter, Sosie - so you can imagine their surprise when they found out they were distantly related.

On the show, presenter Henry Louis Gates Jr showed Kyra a photo of her ninth cousin once removed and - drumroll please - it was none other than a photo of her husband.

"And his name is Kevin Bacon," Henry revealed.

Responding to the bombshell revelation, the Brooklyn Nine-Nine actress - who had already shared her concerns that the programme would reveal them to be related exclaimed: "See. I knew it! I knew it! I knew it! I knew it! I knew it!"

She did, however, assure audiences that the situation was all A-okay, adding: "As long as we’re not first cousins, it’s fine."

Kevin is actually pretty-well known for just how connected he is to a number of fellow A-listers with the 'Six Degrees of Kevin Bacon' game, which is where players challenge each other to arbitrarily choose someone in the film industry and link them through their movie roles to the MaXXXine star within six steps or fewer.

Confused?

Okay, here's an example.

Let's take someone like Ben Affleck who starred in Good Will Hunting alongside Matt Damon who starred in Ocean's Eleven with Julia Roberts, who starred in Flatliners with - you guessed it - Kevin Bacon.

Previously opening up about his opinions on the game, Kevin explained on the On With Mario Lopez podcast last year: "I was horrified! Because I thought it was really a joke at my expense. I just thought, 'Oh come on, they’re just making fun of me, let’s face it!'"

Explaining how he first came to discover the game, he continued: "I heard about it, people would come up to me and say, 'My cousin invented a game about you', or, 'I’m so hungover, I was playing your game last night'.

"I had no idea what they were talking about, I was like, 'I think you’ve got the wrong guy.'"
