Michael J. Fox: Taylor Swift is never, ever, ever dating my son

The lovely and talented Taylor Swift

It's sometimes hard to believe that the country cutie is only 23.

Michael J. Fox does not want his son Sam to be Taylor Swift's next target.

On Sunday's Golden Globes, co-host Tina Fey cautioned the serial dater to stay away from Sam, who was Mr. Golden Globe. "She needs some time to learn about herself," Fey quipped.

Vulture later caught up with the "Family Ties" alum who admitted, "I don't keep up with it all, but Taylor Swift writes songs about everybody she goes out with, right? What a way to build a career."

Fox added that if Sam brought her home, "I wouldn't even know who she was." That is, until he hears her next breakup tune: "'Sam, You Piece of Sh--.' Oh ... that was the girl you brought home!"
