Despite his vague denials, James Franco is dating his “Spring Breakers” co-star Ashley Benson. They were seen holding hands at SXSW in Austin, Texas, where their film premiered. And his recent art show in Berlin, which features pictures of them kissing, was dedicated to Benson. When we first wrote that the pair were dating, Franco blogged, “The New York Post has also been sniffing around for academic gossip because they can’t write about me stumbling out of clubs . . . They can kiss my ass.” We’d rather not.
