In the past they've both laughed off following in Daddy's footsteps.
Leonardo's old Instagram had a few pictures of him on the beach where he pointed out how huge his bulge was in his shorts, but otherwise he's been very focused on athletics and motocross.
Lorenzo mostly posted about how sad he was that his girlfriend dumped him, as they'd been together since they were teens and she was the only girl he'd slept with and so on.
However, lately, both have started posting much more suggestive stuff, lots of showing off their cocks through their underwear and Lorenzo and his new partner doing a semi nude photoshoot.
So I don't think it's beyond the realms that they are embracing the fact that they are famous due to who their parents are and what they do/did for a living, and that the audience they've built is largely there for that... it'll be a very lucrative career for them. Especially in Italy where porn stars are just celebrities, not a late night, dirty secret.
