He is an only child because his twin sisters died during childbirth.
When he was four, Mc Lean began to focus on his love for dance, so his mother signed him up for dance lessons every day for two hours.
He took ballet for four years, jazz, tap, hip hop, rhythm tap, rhythm hip-hop, contemporary, ballroom, salsa, merengue and gymnastics. At age six, Mc Lean was part of a school play, Snow White and the Seven Dwarfs, in which he played Dopey, at Unity of Delray Beach church and school.
His only known appearance on the show is in the pilot episode, which Nickelodeon aired in 1999 as part of its birthday celebration.
When he was 13 years old, Mc Lean tried out for Star Search, but never received a call back from the show.
His mother then got him into modelling when he was around five for a few years, doing J. He also appeared in more traditional musicals such as The Nutcracker, The King and I and Fiddler on the Roof before the age of 11.
