Michael J. Fox can't help but gush over wife Tracy Pollan.
The "Back to the Future" actor took to Instagram on Thursday to celebrate his longtime wife -- and former "Family Ties" co-star -- on her 63rd birthday.
"'She showers the people she loves with love, she shows them the way that she feels,'" Fox's post, which mostly featured photos of him and Pollan together but did include one photo of them with their four children, began.
