Kevin Bacon sent fans into a frenzy as he posed for a selfie and looked completely unrecognisable.

The picture shows the actor with a much fuller, more bloated face and was shared on Kevin's Twitter and Instagram accounts.

The Hollywood star was pictured looking visibly slimmer when he was pictured at the premiere of Adult Beginners in the States just weeks ago.

So either he's been eating too much Bacon, or more likely the look is down to prosthetics for a new acting role.

Kevin captioned the picture: "Greetings from the UK!"

Fans quickly began to speculate why Kevin could be sporting such heavy make-up and a plumper look.

The former Footloose star has been previously transformed himself for a number of high-profile adverts for mobile network operator EE.

One fan wrote: "I smell an EE commercial Mr Bacon. Yay or nay?"

Another said: "I'm pretty sure he's wearing prosthetic makeup for a movie or something."

While another didn't believe it was Kevin at all, saying: "What's going on here?! A UK doppelganger or a new cool app?!"

One fan suggested: "Did you have an allergic reaction to something??? @imkevinbacon"
