Lee was born in Santa Ana, California on April 25, 1970. His father, Greg, was a car dealership manager and his mother, Carol, a homemaker. Lee was raised in Huntington Beach and attended Ocean View High School.
Before he became an actor, Lee was known as a professional Skateboarder in the late 1980s and early 1990s. In 1992, he founded Stereo Sound Agency, known as Stereo Skateboards, with fellow skater Chris "Dune" Pastras. In 2003, after the company had been defunct for a few years, the pair successfully revived the company. As of October 2013, Lee and Pastras remain on the professional "Classics" team roster.
After taking some minor acting roles in 1992–1994 (including the music video for the Sonic Youth single "100%", a small part in Mi Vida Loca, and a bit part as a dance instructor on Chance and Things), Lee left professional skateboarding for a full-time acting career. His first major movie role was in Kevin Smith's Mallrats, which became a cult hit. This started a friendship that subsequently led to appearances in many of Smith's films, including Chasing Amy, Dogma, Jay and Silent Bob Strike Back, Clerks II, and Cop Out. Lee won an Independent Spirit Award for his role in Chasing Amy as Banky Edwards.
Lee married Actress and Photographer Carmen Llywelyn in 1995; they divorced in 2001. Llywelyn later cited Lee's commitment to Scientology as the principal cause for their separation. Llywelyn wrote that their relationship collapsed when she revealed to her talent manager and fellow Scientologist, Gay Ribisi (mother of actor Giovanni Ribisi), that she had read A Piece of Blue Sky, an anti-Scientology book. Two days after her conversation with Ribisi, Llywelyn received a one-paragraph "disconnection letter" from Lee and was labeled a Suppressive Person.
Lee began shooting photos regularly in the early 2000s, and became interested in instant photography. He recently released a photo book through Refueled Magazine. It consists of "184 pages of Polaroid & Fuji Instant Film photographs from 2006-2016." Printed in a limited edition run of 500 copies, the book sold out before shipping began.
Lee was featured in the skateboarding promotional video, Video Days, filmed for the skateboarding company "Blind Skateboards". In 2004, Lee's skateboarding was featured in Way Out East!, a film produced by Stereo Skateboards.
In 2005, Lee was offered the lead role in My Name Is Earl. According to interviews on the first-season DVD, he passed on the series twice before finally agreeing to read for the pilot. In the series, he stars as Earl Hickey. Lee received two Golden Globe nominations for Best Performance by an Actor in a Television Series – Musical or Comedy in 2006 and 2007, as well as a nomination for the Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Comedy Series in 2006. After four seasons of My Name is Earl NBC cancelled the series.
Lee met fashion model and Actress Ceren Alkaç at a concert while on vacation in Britain. Alkaç was born in İzmir, and emigrated with her family from Turkey to Australia soon afterward. Following their initial meeting, the pair stayed in touch via email and texts, with Alkaç subsequently moving to the United States and starting a relationship with Lee. The couple married in California in July 2008; a month later, Alkac gave birth to a daughter named Casper. The couple had their second child, a son named Sonny, in 2012. In 2017, the couple welcomed their third child, a daughter named Alberta 'Birdy' Lee. As of 2016, Lee no longer practices Scientology. Currently Lee resides in Denton, Texas, where he is pursuing photography, and is a co-owner of Barley and Board. He also skateboards in his spare time.
On June 22, 2010, Memphis Beat premiered. In the series, Lee starred with Alfre Woodard and portrayed Dwight Hendricks. In October 2011, it was announced the series was not renewed for a third season. He also guest-starred in 2010 and 2013 episodes of Raising Hope, created by My Name is Earl creator and Producer Greg Garcia.
In August 2012, Lee participated in the ninth annual Stand-Up for Skateparks Event, which he chaired with Tony Hawk. The event is held annually by the Tony Hawk Charitable Foundation and seeks to "help create free, quality public skateparks for youth in low-income communities."
As of December 2011, Lee appeared in Up All Night, but after its second season, it was officially cancelled on May 9, 2013. In June 2013, a fourth installment of the Alvin and the Chipmunks franchise was then announced by the 20th Century Fox studio and a release date of December 18, 2015; it was titled The Road Chip.
Lee's latest projects are with Amazon Studios and The Hallmark Channel. With Amazon Studios, Lee is seen in the pilot of Cocked, where he plays the character of Grady Paxson, one of three men who run a gun Manufacturing company. The show premiered on January 15, 2015 and also stars Brian Dennehy, Diora Baird, Dreama Walker, and Sam Trammell.
