"They looked like normal people, just a husband and wife enjoying the festival," a representative for the Czech Center New York told PEOPLE.
"They came in the early part of the day – around 11 or noon – visited the festival, bought some food and left," said the source for the Czech Center, which organized the festival. "It looked like they might have walked through on a morning walk."
The source added that the couple did not try to draw attention to themselves and politely posed for a photo when approached by festival volunteer Ivana Kovarova.
"I hesitated a little bit to ask because I didn't want to bother them but his wife was just great and said, 'Yes, of course. Why not?'" says Kovarova. "They were eating some Czech meal and sitting at a table. They looked like a normal family – they were just talking to each other and eating."
Duchovny, 48, voluntarily entered a rehabilitation center to treat his sex addition in August, his lawyer Stanton "Larry" Stein told PEOPLE at the time.
