Orlando Bloom was melting hearts at Pier 59 yesterday by playing the devoted dad while his wife, Miranda Kerr, worked on a photo shoot. Spies say Bloom “kept popping up with bottles” to pick up and deliver breast milk for their 3-month-old son, Flynn, who was in his care while the Victoria’s Secret supermodel (who’s already back in amazing shape after the January birth) was working. Earlier this week, he was spotted proudly cradling Flynn as they went through airport security at LAX. His rep didn’t get back to us.
