Kevin Bacon, is that you?
Fans did a double take this week after the 56-year-old actor posted a new photo to Instagram that showed him sporting what looks like a drastically fuller face.
"Greetings from the UK!" is all the caption says.
Is it the work of prosthetics? Makeup? Kevin Bacon eating too much...bacon? Or eggs? He didn't say.
But since "The Following" star looked like his usual self just a few weeks ago (at the premiere of "Adult Beginners" on April 16, as pictured above), we're thinking this new look is just a temporary one.
