Stavros Niarchos III

Part of a legendary Greek shipping family, his namesake grandfather Stavros Niarchos was a rival to Aristotle Onassis, Jackie Kennedy’s second husband.

The third-generation Niarchos, however, appears to have very different interests than his legendary grandfather, having attended USC film school where he graduated in May 2007, intending on a career in film.

However, he is best known for his relationships with Lindsay Lohan, Mary-Kate Olsen and most notably his on-again, off-again relationship with Benji Madden’s one-time other half, Paris Hilton.
