Orlando Bloom and Katy Perry's Bonding Vacay with His Son, Miranda Silent

Orlando Bloom was bombarded with questions about parading around naked on his Italian vacation with Katy Perry, but the photogs didn't see what was right in the actor's hands.

Orlando was cradling 5-year-old Flynn as he left LAX Tuesday, with Katy not far behind. That means, of course, the 3 of them were on vacation together.

We heard rumblings back in February when Orlando and Katy first hooked up ... Miranda Kerr, Flynn's mom, was very unhappy her ex had already introduced their kid to another woman.

Maybe Miranda's ok with Katy being around her kid now that the relationship is more than a fling ... or maybe not.
