Michael J. Fox: Taylor Swift Never, Ever Needs to Date My Son

Actor tells Vulture.com he doesn't keep up with the artist's love life, but isn't keen on her one day writing a song called "Sam, You Piece of S--t"

Could it be that Michael J. Fox doesn't want his son making a cameo in a Taylor Swift song one day? 

During the Golden Globes, hosts Tina Fey and Amy Poehler memorably advised the pop-country star with the increasingly long track record to stay away from Fox's son, Sam Michael, who was serving as Mr. Golden Globes that night.

"Or go for it," Poehler added. "No, she needs some 'me time' to learn about herself," insisted Fey.

The camera panned to Fox multiple times and he was smiling throughout the clever bit. But was that actually a fiercely protective grin he was flashing?

"I don't keep up with it all," Fox told Vulture.com when asked at a book party about the idea of Swift dating 23-year-old Sam. "But Taylor Swift writes songs about everybody she goes out with, right?"

When the reporter answered in the affirmative, Fox replied, "What a way to build a career."

Prodded further, Fox said, "I wouldn't even know who she was" if she showed up at his house on his son's arm. But he'd probably put two and two together, he added, upon the release of the inevitable breakup tune.

"'Sam, You Piece of S--t,'" Fox joked, imagining his reaction. "'Oh...that was the girl you brought home!'"

Fox's rep has not yet returned a request for comment.
