Shauna Roberts is Vincent Chase's publicist who describes herself as Vince's "West-Coast mother". She is a brutally honest woman who speaks her mind to Vince and the boys.
There may be no more frustrating job than being the publicist for a client that doesn't seem to worry about his image. Regardless, Shauna does whatever she can to promote her star client Vince Chase. She also realizes that she doesn't have to take any crap from Vince's friends, and she has no problems putting any of them in their place.
