It seems that Green Lantern star Blake Lively and Leonardo DiCaprio’s hook-up at the Cannes Film Festival may just go the distance. The pair, introduced by director Baz Luhrmann at a group dinner in November, were first spotted getting cozy in May on director Steven Spielberg’s yacht in the South of France. Since then, they’ve been caught connecting in Italy, Monte Carlo, Carmel, Calif., as well as on Lively’s home turf in New York City (as pictured on July 30), where the 23-year-old actress shoots Gossip Girl. But can the summer sizzle last? After all, DiCaprio split with longtime girlfriend, model Bar Refaeli in May, which could make Lively (who’s gracefully handled recent rumors of a nude photo leak) a rebound romance.
