In the fourth episode of Kaulitz & Kaulitz season two, Bill Kaulitz made all the headlines for his very candid remarks about the Swiss people. Following his 35th birthday celebration in Zurich, the leader of the Tokio Hotel expressed his opinions, saying:
"The Swiss are a nice bunch of people and they all look like they have money."
After having what could be more or less described as a great time in Switzerland, the German musician who's been living in Los Angeles for years, said he really wants to go back. On September 1, 2024, the twins celebrated their big birthday at Zurich's Icon Club with their bandmates Gustav Schäfer and Georg Listing.
The whole celebration was shown in their Netflix reality show Kaulitz & Kaulitz, including their shows at Swiss festivals and personal moments with family and friends. Tom’s wife, Heidi Klum, also joined and surprised him with a special gift.
Bill's commentary extended beyond financial observations, as he praised Switzerland's natural beauty and weather conditions during a boat trip to Fischers Fritz restaurant. His enthusiasm culminated in the declaration:
"Look how beautiful it is. Come on, let's move to Switzerland - so green and such great weather."
The episode showcases the twins' relationship dynamics through gift exchanges and reveals their contrasting personalities when faced with adventurous challenges, providing viewers with unfiltered access to their personal celebrations.
Kaulitz & Kaulitz’s birthday party in Zurich and Heidi Klum’s surprise
The Kaulitz twins marked their 35th birthday with an exclusive celebration at Zurich's Icon Club. The venue was reserved entirely for their private party, creating an intimate atmosphere for close friends and family.
Bandmates Georg Listing and Gustav Schäfer joined the festivities, maintaining the group's long-standing friendship bonds. Heidi Klum's presence added star power to the already glamorous celebration.
The timing proved perfect as the twins had performed at two Swiss festivals that same week. They appeared at the Seaside Festival in Spiez BE and the Sunnydays Festival in Arbon TG, making their birthday celebration a wonderful coincidence according to the show.
The party atmosphere continued beyond the club, with celebrations extending to the following morning's activities around Zurich.
The twins broke their tradition of not exchanging birthday presents, leading to amusing revelations about their relationship. Tom presented Bill with a silver box at the Icon Club, captured in Heidi Klum's Instagram story from September.
Bill's initial reaction showed disappointment:
"It doesn't look good ... a small pocket knife ... that sounds like a road trip."
However, the gift proved to be survival training, which Tom explained as payback for Bill's previous road trip gift.
Tom justified his choice by saying:
"I'm sure Bill will learn some useful things during the survival training."
Bill's response was characteristically blunt:
"Useless sh-t ... thanks anyway."
This exchange highlighted their playful rivalry and different approaches to adventure and challenges.
Heidi Klum contributed her own surprise to the Kaulitz & Kaulitz birthday celebrations: shark diving in Hawaii. The announcement triggered strong reactions from both brothers, revealing their individual fears and limitations.
Heidi openly admitted her intentions:
"You're right, because you always make jokes about me and say I'm scared of everything. Now you can see what it's like to be scared."
This moment demonstrated the couple's dynamic and Heidi's strategic approach to addressing her husband's teasing behavior.
Bill expresses his love for Switzerland
The following morning brought a boat trip to Fischers Fritz restaurant, where Kaulitz & Kaulitz's Bill's appreciation for Switzerland reached its peak. His enthusiastic declaration about moving to the country reflected genuine admiration for the scenery and atmosphere.
Bill's earlier comment about Swiss people looking wealthy combined with his praise for the country's beauty suggests a comprehensive positive impression. His Los Angeles residence hasn't diminished his appreciation for European charm and lifestyle.
The episode of Kaulitz & Kaulitz captures Bill considering a significant life change, indicating that the Swiss experience left a lasting impact beyond the birthday celebrations.
