Celebs Work As Hard As We Do: Part 2!

HOUSE OF LIES premieres Sunday, January 8 on Showtime. The series stars Marty Kaan (Don Cheadle), Jeanie Van Der Hooven (Kristen Bell), Clyde Oberholt (Ben Schwartz), Doug Guggenheim (Josh Lawson), Monica Talbot (Dawn Olivieri), Roscoe Kaan (Donis Leonard Jr.) and Jeremia Kaan (Glynn Turman).

In the series, Marty Kaan and his team of MBA-toting management consultants are playing America's one percent for everything they've got. They put the con in consulting as they charm smug, unsuspecting corporate fat cats into closing huge deals, and spending a fortune for their services. Twisting the facts, spinning the numbers, and spouting just enough business school jargon to dazzle the clients, there's no end to what this crew won't do to and for each other, while laughing all the way to the bank. 

In honor of HOUSE OF LIES, we are featuring a gallery of our favorite celebrities doing what they do best. Whether it be in the studio or on a movie set, we like to see them hard at work!
