 Handler has authored two books on the NY TIMES best-sellers list. Handler wrote My Horizontal Life: A Collection of One-Night Stands as her memoir. Handler also wrote Are You There Vodka? It's Me, Chelsea.

In 2007, Handler performed with the Hour Stand-Up Comedy Tour across the U.S.. Her stand-up has been televised on Vh1's Love Lounge, Comedy Central's Premium Blend, and HBO's broadcast of the Aspen Comedy Festival. Chelsea Handler was the host of the highly anticipated Fox show "On The Lot." The show, produced by Steven Spielberg and Mark Burnett, is a competition for aspiring filmmakers who are vying for a chance at stardom. She was replaced after one episode by former Robin & Company entertainment anchor, Adrianna Costa.

In July 2007, Handler began starring on her own half an hour late-night comedy series on E! titled Chelsea Lately. This series places Handler against a slew of male-dominated talk shows, taking both a female approach and adding a considerable amount of sarcasm to the format. On the show's 100th episode, Chelsea revealed to viewers that E! had picked up Chelsea Lately for another 150 episodes.

Since 2007, Handler has appeared in the Internet based program In The Motherhood with Leah Remini and (since January 2008) Jenny McCarthy. The comedic series is about moms, by moms and for moms.
