Michael J. Fox celebrates 'beautiful' wife Tracy Pollan's 64th birthday with loved-up beach photo

It's an extra special, celebratory weekend for Michael J. Fox and his family of six.

The Back to the Future actor, shortly after celebrating his own recent 63rd birthday , is passing the cake to his wife Tracy Pollan , who rang in her 64th trip around the sun on June 22.

The Parkinson's activist and his wife, who met while starring together in Family Ties and have been married for over three decades , share son Sam, who also turned 35 some weeks ago , twin daughters Aquinnah and Schuyler, 29, and Esmé, 22.

To honor Tracy's birthday, Michael took to Instagram on Saturday and first shared a stunning, black-and-white portrait of her, followed by a sweet, sun-filled photo of the two together at the beach.

"In every beautiful way, it's beautiful Tracy's beautiful day," Michael wrote in his caption, adding: "I love you and today will be magnificent."
