Heidi Klum is celebrating a relationship milestone with husband Tom Kaulitz … and they’re partying hard.

The supermodel just posted videos and photos from her 6-year wedding anniversary celebration with the Tokio Hotel guitarist … and there are bikinis, infinity pools, Champagne, gifts, kisses and club hopping … oh, and some feet videos, for those of you who enjoy that sort of thing.

Heidi and Tom are somewhere in paradise celebrating their marriage … and they look super happy.

They opened presents, sipped some Veuve Clicquot bubbly, made out in the pool then got ready and went to a day party.

Hard to believe Heidi is 52 … she’s still keeping up with 35-year-old Tom.

Heidi captioned her post … “6 Years married today.” She also said “I love you my Tom” in German.

The couple is actually celebrating the anniversary of their second wedding … we broke the story, they got secretly married in Los Angeles in February 2019 before getting married again in August 2019 on a yacht in Italy.

Six years later and it looks like they’re still going strong!!!
