Steven Spielberg and Kate Capshaw
Given Spielberg's remarkable movie successes, this couple was destined for this list. Kate Capshaw has been steadfastly by his side throughout. They've been together for an impressive 32 years and are parents to seven children, a blend of their own and from previous relationships.
Kate, a retired actress, met Spielberg on the set of Indiana Jones and the Temple of Doom. In a 1995 interview, she reflected on their relationship, "We're always pushing our envelopes." The couple's net worth is $5.4 billion.
