Click on the photo below for an adorable gallery of Miranda and Flynn.
The Australian-born supermodel planted a tender kiss on her two-year-old son's lips, as Flynn looked up at his mother and beamed away.
The mother-son duo shared a giggle and looked lost in the moment as they spent a relaxed Sunday afternoon strolling around the Big Apple streets.
Miranda looked chic as ever in a full-length blue maxi dress, printed with gorgeous flowers. The former Victoria's Secret angel completed her outfit with oversized aviator sunglasses and a black leather handbag, and swept her luscious brunette locks into a loose plait.
Little Flynn dressed just as cool as his mother in dark jeans and a casual khaki jumper. Wearing bright neon trainers and a grey baseball cap, the adorable tot looked right on-trend and fitted in with his model mum's style.
Miranda, who is married to Orlando Bloom, has clearly got a lot of love for Flynn. The doting mother is quick to show off cute photographs on her Instagram account, much to the delight of her fans.
"There is nothing greater than a mother's love ❤," wrote Miranda, alongside one snapshot of her cradling a sleeping Flynn.
"To love and be loved is one of the greatest gifts in the world ❤🌊☀," she posted soon after, next to a photo of herself in a leopard-print bikini, forming the shape of a heart with her hands.
