Jessica Biel is one lucky lady!

Justin Timberlake just debuted the music video for his single "Mirrors", and we think it's so sweet that he drew inspiration for it from his grandparents William and Sadie!

The "Suit & Tie" crooner's grandfather passed away last year, and the video captures a couple's love story through several generations as a tribute.

With lyrics like "I'm lookin' right at the other half of me/The vacancy that sat in my heart/Is a space that now you hold", we think he's also paying homage to his new wife and envisioning growing old with her.

We couldn't be happier JT is back to making hits!
