Heidi Klum and Tom Kaulitz rang in their first wedding anniversary with an epic cake depicting the very yacht they were married on exactly a year ago, and it's immediately evident that they are still very, very much in love.

The cake is a beautifully detailed depiction of Christina O, which is the name of the vessel they rented for their lavish nuptials. Clearly an oversized cake with "Happy Anniversary" written in cursive, and blue ocean accents throughout, we're not sure if they're planning to eat this cake or simply sit back and admire it! This cake is complete with cake toppers depicting the couple, along with an array of multicultural guests sitting on the deck below.

The couple posed for their anniversary photo, reminiscing about the romantic waters in Capri, Italy where they were married just a year ago. True to form, this was an incredibly detailed, perfectly planned celebrity wedding and was truly the celebration of a lifetime. Klum and Kaulitz tied the knot while surrounded by their closest friends and family, which included a star-studded guest list. Their wedding on the water was every bit as exquisite as you'd imagine it to be.

Happy Anniversary!

A year ago, Heidi and Tom welcomed their guests aboard The Christina-O, which is far from being an ordinary yacht. Considered to be one of the most magical and historically significant celebrity yachts, it very much deserved to be front and center in the form of an anniversary cake! This incredible ship "once belonged to billionaire Greek shipowner Aristotle Onassis." It's a monstrosity of a boat, too, 99.13 meters long, and "was the 45th largest yacht in the world as of 2018." It costs nearly a million dollars a week to rent, and is worth every penny if you're looking to live the high life on the high seas.

The amenities on the yacht will leave you breathless. The special features you'll find about this ship are advanced and luxurious, inclusive of an onboard pool that has a floor which can be raised to form a dance floor! The boat boasts a salon, a spiral wooden staircase, and room so big you'll get lost in them.

Guests that have privately rented this incredible yacht have included Marilyn Monroe, Frank Sinatra, John F. Kennedy, and Winston Churchill, to name a few.

Recreating their blissful wedding by having a cake made to mimic Christina-O is a true nod to the significance this ship has to Heidi Klum and Tom Kaulitz. While some couples gush love for one another and declare their undying affection and dedication to sharing a future hand-in-hand, Klum and Kaulitz are dedicating their joyful memories to a vessel they love and cherish, and clearly have a strong connection to. Choosing a wedding venue is not easy, and clearly this  boat carries a lot of significance to the couple. They captioned their photo with the comment; "We miss you ⚓️💦Christina O ❤️"
