It’s a question we didn’t know we needed answered until Lady Gaga brought it up. In a tease of her sit-down with Anderson Cooper airing Sunday on CBS’ 60 Minutes before the Grammys, Cooper asks her what he should call her. “Gaga,” she says. Some people call her Stefani, her given name, she admits. “Especially in bed,” she says. “I prefer Stefani in bed.” Watch the clip here. I like how soft and (almost) natural she looks for their chat. My hope is that in addition to more revealing patter, she gets him to giggle like Kathy Griffin did on New Year’s Eve. The man deserves a laugh.
