NORA'S ARCH: No wonder Nora Arnezeder is glowing. The French actress, who sat front row at the John Richmond show in Milan, has been working with some pretty hot male co-stars, including Ryan Reynolds, who is having a Hollywood moment. "He's an extraordinary actor," raved Arnezeder, who stars opposite him in the upcoming "Safe House." "I play his girlfriend, but I can't reveal any more." She has two further films in the can: “The Words,” co-starring Zoe Saldana and Bradley Cooper, and French director Alexandre Arcady’s “What the Day Owes the Night.” In between promotional duties, Arnezeder plans to spend the next few months working on her debut album. "It's very slow," she said of the recording process. "I want to take my time to produce something good that reflects who I am."
