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."
He concluded: "Always forever your Mike with so-much love. Happy birthday. It's gonna be an epic day," signing off with a red heart emoji.
Fans were then quick to take to the comments section under the post to gush over the tribute and further celebrate Tracy, with one writing: "Happy Birthday Tracy! You both exemplify what love and dedication truly is!" as others followed suit with: "Happy Birthday Tracy, you are a true beauty inside and out!" and: "Happy birthday Tracy!! Make your special day spectacular and memorable!!" as well as: "Happy Birthday, Tracy! May all your blessings and memories be filled with faith, hope and love today and every day!"

For Michael's own recent birthday, Tracy similarly shared a portrait of her hubby, followed by another one of the two together at the same beach but on a different occasion.
"Happy birthday Mike!" she started, and declared: "Cannot wait to celebrate all summer long!"

Michael wrote back in the comments section: "I'm so lucky in love!" and was subsequently inundated with more birthday messages from fellow celebrity friends like Deborah Roberts, Ali Wentworth, Julianne Moore, Jennifer Grey, Katie Couric, and Hannah Waddingham, among others.
And though his youngest daughters have private social media accounts, his son Sam also shared a public birthday tribute, posting a photo of his dad shaking hands with former basketball player Blake Griffin, and joking: "Happy birthday Pops!! You might not be the tallest guy in the world, but you're still my favorite. Love you," to which Michael joked back: "I can make 3 suits out of @blakegriffin23's jacket alone."
