Hilary and Haylie Duff are one of Hollywood's cutest pairs of sisters [1]. The duo looked gorgeous on Tuesday when they stepped out for a sunny stroll in New York City. Hilary and Haylie both flashed massive smiles for photographers as they left a taping of Good Day New York.

The cute outing comes a few weeks after Hilary showed off her insane bikini body [2] during a Hawaiian getaway with her son, Luca, and a group of friends. Haylie didn't tag along on the vacation because she's a new mom to her adorable daughter, Ryan [3], whom she welcomed in May with her fiancé, Matt Rosenberg [4]. See Hilary and Haylie's sisterly love above, then check out Hilary's cutest moments with Luca [5].
