Sylt hermit Mark Medlock posts first photo in 20 months - fans don't recognize the DSDS winner. Medlock is wearing a casual leisure look with sweatpants and, unlike before, appears clean-shaven except for a prominent mustache.

The photo received almost 3,000 likes in the first three days. Many are just happy to hear from him again: “The main thing is that you’re doing well. It’s nice to read something from you,” it says.
