In case you were wondering (and we were), Kate Winslet will not be taking her new husband’s last name, which is Rock’nroll. “I quite like Kate Winslet; in fact I think it’s very flashy,” she also told Us Weekly, which is strange, because “Kate Rock’nroll” is pretty much the definition of a flashy name. Well, we still have hope for their future child, Leonardo diRock’nroll.
