THE EX FACTOR

After two years together, Diaz and her There's Something About Mary costar Matt Dillon (left, at the movie's L.A. premiere in July 1998) broke things off in the fall of '98. A year later, Diaz fell for another actor, Jared Leto (in Malibu in 2000), but that relationship ended in 2003.
