Celine Dion and Leonardo DiCaprio at the Titanic premiere in 1997

Celine Dion was 29 and Leo was 23 at the time for reference. The Titanic would go on to gross over $1 billion, becoming the first movie to do so. Humorously, they both still look about the same age as they do in this photo, showing that celebrities are capable of not aging in the modern era. Whether they have "the One Ring" or are Elves, we're aren't privy to that information, but we can speculate.
