Jessica Simpson spends time with ex assistant CaCee Cobb in Calabasas at restaurant Houston

Jessica Simpson's new assistant has reportedly said she is "too smart" to work for the blonde star. Jessica hired Adrienne Sands - a graduate of the University of Wisconsin - to replace her former assistant Cacee Cobb. However, Sands is seemingly unhappy with her new job and wants to quit.

A source close to Jessica told the New York Post newspaper: "Adrienne has been telling everyone she's too smart for this job and doesn't like it." The alleged conflict comes weeks after Jessica's father fired her publicist.
