After being in the spotlight for more than 30 years, it's hard to find Kevin Bacon unrecognizable, as there's even a parlor game involving him ("Six Degrees of Kevin Bacon") that works under the theory that everyone in the world is linked to the actor through six people or less.

However, in a recent selfie, Kevin Bacon's unrecognizable nature became apparent, as the Golden Globe winner posted a picture of himself looking incredibly bloated, making many wonder whether he'd recently gone through heavy plastic surgery in his face, like the recent scandals involving Oscar-winning actress Renee Zellweger and Quentin Tarantino's muse Uma Thurman.

According to People Magazine, Kevin Bacon's unrecognizable look first appeared on the actor's Instagram and Twitter accounts, as he posted a selfie in what appears to be a film set of some sort, looking completely different from the way he usually does - that is, very bloated, unlike his usual slim figure.

"Greetings from the UK!" was the caption beneath the Kevin Bacon unrecognizable photo.

According to Entertainment Tonight, though, the Kevin Bacon unrecognizable pic must be due to prosthetics and makeup, as the actor was looking just like his usual lean self less than a month ago on the Hollywood premiere of "Adult Beginners" - but it's unclear what exactly the "Following" actor is working on in the UK that would require this type of prosthetics, as his IMDb page doesn't list any current projects being filmed.

However, Yahoo! News reports that the actor, famous for not taking himself seriously, has often said he's walked around Hollywood in heavy prosthetics to avoid being recognized, so maybe he's just showing off his strategy - though that could potentially be a very bad idea, as it would mean he's making his "fake" face public and possible to locate when walking around in Hollywood for a cup of coffee.

In any case, Kevin Bacon IS unrecognizable in the photo!
