Heidi Klum and her husband, Tom Kaulitz, looked like they had the best time ever at her son Henry's high school graduation. On Friday, June 7, Klum shared a video of Henry receiving his diploma on stage. In the Instagram post, she also included a clip of her and Kaulitz smiling while sitting in the audience.

After the ceremony, Klum posted a snap of her, Kaulitz and her children, whom she shares with ex-husband Seal, dining out at a restaurant while celebratory balloons sat in the middle of the table. She captioned that post, "Celebrating HENRY ❤️🥰🎉." On many occasions, Klum has called Kaulitz the love of her life.

The pair swapped vows in 2019, making him husband No. 3 for the supermodel-turned-reality TV entertainer. And it seems Klum — who was previously married to stylist Ric Pipino (from 1997 to 2002) and to soulful singer-songwriter Seal (from 2005 to 2014) — believes the third time's a charm.

She's repeatedly dubbed Kaulitz the "love of my life" on Instagram. The many kiss-filled photos and video clips of herself alongside her bearded spouse appear to prove that the sentiment is mutual. He's her frequent red-carpet date.

He's her "beautiful and cute" partner. He's even a perfectly coordinated plus-one at her annual Halloween bash. But there's so much more to know about him.
