Being married to Larry Ellison seems to be more of a part time job than a lifelong commitment. The Oracle Corporation founder, who has an estimated worth of over $50bn, is now on his fifth wife, Nikita Khan.
Kahn is known for her philanthropy, and has a particular interest in wildlife conservation. She's raised millions for the California Wildlife Center, and also uses her talents as a filmmaker to raise awareness about environmental issues in documentaries like 'The Last Animals.'
