Orlando Bloom showed why he's one of Hollywood's hottest dads on Sunday as he strapped baby son Flynn to his back and took him on a hike in L.A.'s Runyon Canyon Park.
Bloom expertly incorporated Flynn, who turns 1 year old on Jan. 6, into his exercise routine with two male friends.
With his wife, Flynn's mom Miranda Kerr, nowhere in sight, Bloom toted Flynn on his back in a baby carrier while holding a water bottle in one hand and the leash of his dog, a black Saluki mix named Sidi, in the other.
As RadarOnline.com has previously reported, Bloom has no problem giving his Australian model wife a break and being Mr. Mom with his son.
The actor flashed his wide smile as he walked along with an unfazed Flynn bouncing in his Bjorn behind his dad. And it was sure to be a great workout, as Flynn is a big boy who weighed in at 9 pounds, 12 ounces at birth!
