She was voiced by the late comedian Joan Rivers.
In the mid 1960s, she was an agent looking for some new talent, or a fourth husband, when she came across Krusty, who back then was performing at jazz clubs, but neither the less, was still funny. She saw potential in him, and after his show went to talk to him at a nearby restaurant.
She talked about how she could mold him into a star, but he needed a new look and then told him to change his comedy style, which was considered the "cheap" kind. Krusty then told her that he would only want to be with her. Every night after Krusty's show was done, they would have sex, but one night while in bed, he betrayed her by moving on to other agents and businesses. In a fit of rage she kicked him out of the hotel room and called him an ungrateful pig, as she was the one who made him a star. Due to this, she didn't have sex with a clown for 5 months.
When she was scouting clients, she discovered Krusty and grew more fond of him after each show and helped his career. They would have sex in the hotel that they were staying at, only to later be betrayed by him. She moved on and worked for other stars, claiming she would work for only 10%.
She managed to get him a show at the Springfield Playhouse, where he performed his show for adults. He was, at first nervous but she gave him courage to perform. After his show was a success, they made out in the coat room. She congratulated Krusty and managed to get him a new premium subscriber network. From there she showed a different side of herself the real Annie who is a very demanding one. Due to this, the network asked Krusty to fire her.He kept his promise and didn't. They got on a new show called "Sex Over Sixty", whereas the show's title says, they had sex.
Her trust is described as being like the flame on a flickering candle, once it blows out, it's gone for good. She can be very nice and she wants to, giving encouraging advice and can get you a minor role on a well known show.
When it came to show biz, she showed a different side of her, a one that is very demanding and won't stop till she gets what she wants. She got angry when the set wouldn't paint something right, had a fit when a monkey by accident upstaged Krusty, and the worst one of all was when he broke the legs of an intern by driving a golf ball cart at him just because she claimed he sharpened her pencil "to sharp". They planned on firing her, by because of Krusty's promise, they went to a different TV station.
She is described as having white/blonde like hair, wearing white earrings, and a necklace. Her outfit consisted of a sky blue jacket over a light blue dress, and black shoes. She also wore a dark blue purse with a brown bracelet.
According to her, she has had three husbands.
