On L.A.’s artsy east side, Christina Hendricks and her hubby, Geoffrey Arend, were a constant fixture — hanging out at said Mexican restaurant, walking down the street past the shipping supply store and the nail salon and doing “normal” things. But the Mad Men star has now decamped from New York, as she told Mark Ronson from the front row of Zac Posen’s fall 2015 show during New York Fashion Week on Monday. Hendricks told the British-born musician and his wife, model-actress Josephine de la Baume, just before Posen sent the likes of Naomi Campbell out on the catwalk, “We live here now. We’re New Yorkers again. It’s kind of fun.” Arend, a fellow thespian, is currently appearing in the CBS hit Madame Secretary, which films in New York. So the couple headed east.
