Michael J. Fox agrees with Tina Fey: Taylor Swift should stay away from his son. When asked whether he’d approve of the pop star dating his 23-year-old, Fox was adamant, “No. No ... Just back off.” The actor admitted to New York magazine blog Vulture that he doesn’t really keep up with entertainment news, yet even he knows that T-Swift has a tendency to use her many relationships for song material. “What a way to build a career.” If Sam brought Taylor home to meet his parents, Fox said he probably wouldn’t know who she was—until he heard her newest ballad on the radio. “Yeah, exactly. ‘Sam, You Piece of Shit.’ Oh ... that was the girl you brought home!”
