Orlando Bloom Flynn Hollywood Hills OBloomFlynn033012_25_X1.jpg

Orlando Bloom took his nearly 16-month-old son Flynn for a hike in the Hollywood Hills yesterday, and we can't get over how adorable the celebritot is! I guess that's what happens when someone as handsome as Orly has a baby with a Victoria's Secret model...

The 35-year-old actor was joined by longtime pal Enrique Murciano, and while we would make a crack about Orly's blue baby backpack, check out Enrique's leggings ... they're almost distracting us from Flynn's little precious face!
