Michael J. Fox Does Not Want Taylor Swift To Date His Son (UPDATE)

With age comes wisdom, and Michael J. Fox has the good sense to listen to Tina Fey.

Recall last week's Golden Globe Awards, when Fey took a playful jab at serial dater Taylor Swift, telling her to stay away from the "Back to the Future" star's 23-year-old son, Sam? Well, Fox was paying attention.

Vulture caught up with the 51-year-old actor at a book launch party in New York City, and told the website that he wouldn't approve of Taylor Swift dating his son.

"I don’t keep up with it all. But Taylor Swift writes songs about everybody she goes out with, right?" he asked, adding, "What a way to build a career."

Fox really doesn't keep up with the rumblings of young Hollywood, as he admitted that if his son brought her home, he probably wouldn't even know who she was -- but he'd probably be able to put two and two together if he heard the inveitable song Swift would pen about the romance.

"Yeah, exactly," he said. "'Sam, You Piece of Shit.' Oh … that was the girl you brought home," he joked.

Clearly, Fox has a bit more foresight into this than Swift's most recent romantic conquests, which include One Direction's Harry Styles and Conor Kennedy, both 18, and five years Swift's junior. And Fox has good reason to worry that Swift would seek musical vengence. In fact, soon after the 23-year-old superstar split from Styles, she tweeted an ominious message:

Swift knows she's made a career for herself exposing her personal life, but with tweets like that, it's almost as if Swift is banking on romances turning sour in order to inspire her next big hit.

UPDATE: It seems that Fox might have felt a little bit guilty about his comments, so he called Swift up and they are totally cool now.
