The 43-year-old actress was in New York City when she was stopped by a group of police officers.
Surprisingly, one of them asked the former wife of Ben Affleck to take a selfie with him. An eyewitness said that Garner was in a good mood and she immediately accepted the officer's request, reported Ace Showbiz.
"She was walking alone, just going about her day. The officers saw Jen and asked if she would take a photo with them, which she obliged," a source said.
Last week, the mother of three was photographed at a market in Pacific Palisades, where she grabbed some fresh fruit and vegetables.
On the previous day, she was pictured leaving the gym to pick up her children from school.
