And she later got into even move Bavarian spirit with a giant pretzel dunked in a vat of chocolate.

Heidi, 52, was with husband Tom Kaulitz at the bash, along with children Leni Klum, 21, Henry Samuel, 20, Johan Samuel, 18, and Lou Samuel, 15.

She previously said of her brood: “For me, it’s always the more, the merrier.”

It comes after Heidi recently enjoyed a sun-soaked vacation with her husband.

Speaking about Tom in an interview, Heidi gushed that she had “finally found the one” in her husband.

“I just know him so well. We just gel really well,” Heidi spilled in an interview with E! News.

“I just feel like, ‘Finally, I found the one.’ So far so good. I hope it stays that way.”

And last year she even lifted the lid on their sex life.

Speaking about their “bedroom sports”, Heidi told The Sunday Times: “Sport en chambre is my favorite exercise — it sounds better in French.

“I have a younger husband,” she gushed.
