Audrey has the same facial structure as Arianna Jalowitz. According to her SimDNA in SimPE, her hair was black before it turned grey. Audrey's name is randomized when La Fiesta Tech is generated. The name "Audrey Larrea" is only referenced in the game files. Even though Audrey is thin, her fitness level indicates that she is supposed to be fit. This happens with all coaches from The Sims 2.
