Comedian Greg Behrendt is the co-author of the two-million-copy bestseller, "He's Just Not That Into You," establishing himself as a voice of reason and inspiration for all of us negotiating, and sometimes drowning in, the treacherous waters of romantic relationships.

Co-authored with "Sex and the City" story editor, Liz Tuccillo, the book became the publishing phenomenon of the year after its release in September 2004. The book shot to the #1 slot on the bestseller lists worldwide, including The New York Times, Wall Street Journal and USA Today. Oprah Winfrey devoted two shows to Greg and the book's simple, but powerful message. Behrendt also made numerous television appearances including NBC's "Today Show," "20/20" and "Larry King Live" on CNN. After a fierce bidding war, New Line Cinema acquired the film rights to "He's Just Not That Into You" with the co-authors penning the script.

Behrendt, with his wife and co-author Amiira Ruotola-Behrendt, released a follow-up relationship book through Broadway Books/Random House. Offering straight talk, tough love, and hilarious (yet useful) tips on how to survive and get over break-ups, the book, titled "It's Called a Break-Up Because It's Broken," immediately jumped to the top of the book charts again. Over a month after appearing in stores, the book is still climbing the bestseller lists, including the Wall Street Journal, Amazon.com, Barnes & Noble.com, and The New York Times.

Warner Bros. released his debut DVD, "Greg Behrendt is Uncool," which is the follow-up to his comedy CD entitled, "UNCOOL." "UNCOOL" is the examination of a rocker turned suburban Dad struggling to hang on to his last threads of coolness. It explores the evolution of the male psyche while bucking the conventional entry into maturity. Behrendt brings his deepest, darkest fears of becoming a no-longer-relevant Gen-Xer to the surface, deconstructs the notion of "cool" and offers in its place a new definition for adulthood.

Behrendt is the host of "The Greg Behrendt Show" for Sony Pictures Television. The show features Behrendt's signature humor and advice when it comes to all kinds of relationships ;including those with family, friends, romantic partners and relationships in the workplace. He has also signed on with ABC to create a primetime reality show that will propel him further into the enigmatic world of relationships. On the show, men and women in relationships will be tested to determine their level of compatibility as couples. With a sardonic honesty similar to that of his books and stand-up, Behrendt will lead the couples through various analysis tools and exercises to assess their future together.

Based in Los Angeles, Behrendt was a consultant for three consecutive seasons on HBO's "Sex and the City" in which he brought his original male point-of-view to the writing staff. His acclaimed stand-up comedy has been seen on HBO, "The Tonight Show," "Late Show w/David Letterman," "Late Night with Conan O'Brien" and Comedy Central. He was named by Variety in 2001 as one of the "10 Comics to Watch." This month he was honored by COSMOPOLITAN magazine as one of the twelve "Fun, Fearless Males" along with Patrick Dempsey and Nick Lachey.
