Michael Douglas Lohan II was born on December 16, 1987 in New York, New York to Michael and Dina Lohan. He is the younger brother of star Lindsay Lohan (b. July 2, 1986), and the older brother of Aliana Lohan (b. December 22, 1993) and Dakota "Cody" Lohan (b. June 16, 1996). Michael's first and only film role was in Disney's The Parent Trap (1998), where he played the Lost Boy at Camp.

When he was young, he used to travel with his mother and younger siblings while Lindsay was in movies, and they were uncredited extras in the films. He was also a Ford Model, similar to his brother Cody and sisters Lindsay and Aliana. When Lindsay took some time off from acting in 2001, Michael did, too. But instead of traveling from film set to film set when Lindsay went back to acting, Michael decided to stay in high school in New York. He graduated from a Long Island high school in 2005.
