Nearly 35 years later, Michael J. Fox and Tracy Pollan are just as much in love, as evidenced by the actor's sweet tribute to his wife on her birthday.
Michael, 62, took to Instagram with a slew of photos of his wife, who turns 63 today, pairing amorous vacation shots together with some solo photos.
He also included a picture of their entire family, alongside their four children, son Sam, 34, twin daughters Aquinnah and Schuyler, 28, and youngest Esmé, 21.
The caption alongside the post read: "'She showers the people she loves with love, she shows them the way that she feels'. Happy happy birthday @tracy.pollan my forever Summer girl, my love, my best friend, and the most beautiful amazing mom to our four stupendous kids. Love love love you."

Speaking with People at the SXSW premiere of Still: A Michael J. Fox Movie in March, the couple gushed about their relationship and how they continue to support one another.
