Ashley Boulet (a.k.a. Ashley B.), is the second-in-command of the Ashleys clique in the series.
Ashley B. is slender, of average height, and is African-American part French. She has curly black hair that goes down to her chin with a yellow barette on the sides of her head. She usually wears a white shirt with a yellow blazer/sweater, a plaid yellow skirt, long white socks, and black chunky-heeled shoes. She also wears red lipstick and a necklace with a gold pendent on it.
Like the other Ashleys, Ashley B. is just as snobby, and is considerably more sarcastic and prissy than the other girls. She is primarily interested in fashion and gossip. She met the other Ashleys one day in kindergarten at a playground, where all their hats were blown off their heads, and when they tried to get them, they bumped into each other and introduced themselves, becoming friends. Since then, the anniversary of when they first met has been known as "Purple Day", as the girls all wore purple when they met, and thus only purple can be worn on "Purple Day". When Ashley A. accidentally forgot to wear purple on that day, Ashley B. kicked her out of the clique and quickly took over leadership position. Though by the end of the episode, they made up.
Ashley B. is considered the closest to Ashley A., as they're usually seen together more often than the other Ashleys. She has also shown to be quite nice in certain situations as well.
Ashley B. lives with both of her parents. Her mother, who has only been seen in "Parents Night", has been shown to look and act just like her. Her father has never been shown on screen, but has been mentioned a few times. She has a younger brother named Tyler, who's seven years old and in second grade, and a member of rich boy clique the Tylers, and she has a five year old sister in kindergarten, Brittney, who hasn't been shown in a clique with the other Brittneys.
