Kevin Bacon shocked many on Monday when he shared a selfie via Instagram that looked nothing like him!

Ashton Kutcher's Gift For His Mom For Mother's Day Outdoes Every Other Gift Imaginable

In the photo, which is above, the 56-year-old actor appears to be wearing prosthetic make-up since his face is rather puffy. His cheeks are quite puffed out, which is not his usual appearance. He typically has a thinner face.

Is it for a new acting gig? Is it for a new commercial? Or has The Following star fooled the masses by using a mobile app that can manipulate his face?

Kevin Bacon Found His TV Niche Through 'The Following'?

Well, we don't know! But we do know the actor is in the United Kingdom at the moment. In the selfie he looks like he is standing in front of a trailer on a set of a movie, TV show or commercial. It could be his trailer or perhaps a make-up trailer.

In the caption of the unrecognizable selfie, he shared, "Greetings from the UK!"

On Twitter, the entertainer also shared the selfie and many bacon jokes arose as seen below.

Fat jokes in general came up too. One Twitter user insisted Bacon "ate a lot of pies since the weekend!"

Bacon has yet to say what the deal is with his unrecognizable selfie.
