This comes only 3 months after OK! reported in mid May that the couple had decided to call it quits after being together nearly a year.
Around the same time, The Daily Show host, 37, bought a gorgeous Bel Air mansion, fueling further rumors that the lovebirds may be getting more serious about the future. The spacious home boasted 6 bedrooms, 11 bathrooms, a movie theatre, a gym, a spa, a library, a game room, ample office space, and a sun deck with a pool.
Only a few months later, outlets reported that Noah and Kelly had called off their relationship. An insider dished the news to Entertainment Tonight, saying, "Their work commitments and careers are very different and they both felt like they should take time apart."
The insider also mentioned that Kelly, 41, healed from the breakup by "leaning on friends, traveling and keeping busy since their split."
Prior to her relationship with the popular show host, The Roommate leading lady was linked to Grey's Anatomy star, Jesse Williams.
But now, the pair seem to at least still be friends.
The stunning brunette beauty was all smiles during their walk, dressed in a chic, beige ensemble and a pair of dark lens sunnies, while Noah sported a comfortable and casual look, wearing a white tee and a grey pants.
The Afraid of the Dark comic seemed to either be on a call, or taking pictures — though if it was of paparazzi or just taking in the New York City scenery, it's hard to say — while he dutifully held the dog's leash.
Fred himself was also looking absolutely fabulous and carefree in a green, floral patterned bandana.
