Well, the answer is that they have all dated Tom Cruise -- we are sure you got that -- and they are all taller than Tom, as is evident in this picture of him and wife Katie Holmes during the German premiere of the actor's film Lions For Lambs at the Kino International Theater in Berlin on Wednesday.
The jetsetting couple was in Berlin just after the film's premiere in London.
Cruise stars as a charismatic senator along with two-time Academy Award winner Meryl Streep and Academy Award winner Robert Redford in this film about the complex nature of war.
Streep plays the role of a television journalist while Redford plays a professor.
