William Luca Costa-Marsden is a son of actor James Marsden and Brazilian model Rose Costa. Though their love affair was pretty short, the news about Rose’s pregnancy appeared in June 2012 and in December, William drew his first breath.
Rose prefers to call her son Luca and frequently shares his photos on her Instagram. The boy seems to have a very bright childhood. He often travels, does yoga and skiing as well as takes art classes.
A curious fact: though the boy rarely appears in public, William and his half-sister Mary attended the Sonic the Hedgehog Family Day Event with James in 2020.
