Heidi Klum proves she is the hostess with the mostest at her first ever pre‑Oktoberfest party — ‘HeidiFest’ — in Munich, Germany on Friday … getting absolutely soaked in some good ‘ol Hofbräuhaus beer.

The supermodel participated in a traditional keg tapping ceremony — similar to what you’d see at Oktoberfest — and seems to accidentally shower herself with beer during that traditional moment … and we’re certainly not complaining.

Klum was joined by her husband Tom Kaulitz, brother-in-law Bill Kaulitz, her mother Erna Klum, and her kids with ex-husband Seal — Leni Klum, Henry Samuel, Johan Samuel, and Lou Klum — to celebrate the Bavarian traditions.
