WTF LOS ANGELES, May 6 (UPI) -- Twitter users are wondering what's behind Kevin Bacon's new look. The 56-year-old actor has an unrecognizably bloated face in a photo he posted to the social media site on Monday. "Greetings from the UK!" Bacon captioned the photo. Bacon offered no explanation for the sudden change in his appearance, though he looked much like his usual self at the Adult Beginners premiere last month.
