Kristen Bell has reportedly joined the cast of 'House Of Lies'.

The 'Veronica Mars' actress is said to be joining Don Cheadle and Dawn Olivieri in the Showtime pilot and is tipped to play Jeannie, a smart graduate who reluctantly finds herself attracted to her co-worker Marty, played by Don.

The prospective series – based on Martin Kihn’s best-selling book 'Lies: How Management Consultants Steal Your Watch and Tell You the Time' - will be spearheaded by Matthew Carnahan of 'Dirt' success.

It's been a good year already for the blonde beauty, who last week was announced as the new face of cosmetics firm Neutrogena.

She said: "I am really excited to be the new face of Neutrogena Naturals because I trust the brand so much already. I strive to live a healthy lifestyle, and to be able to represent a line that I actually use and like to incorporate into my daily routine is ideal."
