Blake Lively and Leonardo DiCaprio took a stroll in the Mediterranean city of Portofino over the weekend. Leo and Blake were careful not to show any PDA, but he was right behind her leaving the town's center with ice cream cones. The duo headed to Italy after Cannes, where they were seen together at the Hotel du Cap and on Steven Spielberg's yacht. They parted ways yesterday, though, when Leo jetted to another Italian city to meet up with Naomi Campbell and her boyfriend, Vladislav Doronin, to start celebrating the supermodel's 40th birthday. Leo is moving right along since his recent split from Bar Refaeli, and Blake seems to be doing the same since parting ways with Penn Badgley last year. If Leo and Blake are dating, they seem to be taking it slow. They both enjoyed solo time during the film festival, with Leo stepping out to honor Sean Penn's Haiti efforts with a dinner and Blake hitting Antibes for Chanel's resort collection.
