"Happy 7 anniversary my love!" Bundchen, 35, captioned a photo of the couple's hands. "Thank you for always being by my side. I love you!"
In the pic, Bundchen and the New England Patriots quarterback, 38, wear their gold wedding bands, which they exchanged at a ceremony in 2009.
The couple dated three years before marrying and are the parents of son Benjamin, 6, and daughter Vivian, 3. Brady also has an 8-year-old son John with ex-girlfriend Bridget Moynahan.
Bundchen opened up about her romance with the athlete — and the bumps they've endured over the years — during an interview with CBS This Morning back in November. The sit-down took place three months after Us Weekly exclusively revealed that Bundchen had threatened divorce amid his Deflategate scandal.
"I think we've been through a few tough times together," she told host Charlie Rose. "I think that's when you know who are your friends and who loves you. My father always said the quality of your life depends on the quality of your relationships, and I think, no matter how challenging it was, we've always been supportive of one another. I think that's the most important thing you can have in life, you know? A support system and love."
Weeks later, Brady posted a sweet photo of Bundchen decorating their Christmas tree and called her "the love of my life."
