- 非法持有毒品: 在“蠢婊子摄影套装”中，她告诉温蒂·泰斯伯格在她家的聚会中会有K粉（可他名）和一些第三级麻醉性毒品。
Bebe has long, frizzy golden blonde hair, parted to her left side. While her hair hangs down to about her right elbow, she was seen in "Informative Murder Porn" with some of it draped over her left shoulder. It was mentioned by Wendy in "The Hobbit" that she has acne. She wears a red jacket with light gray trim and dark green pants with light gray mittens on her hands. Underneath her jacket, she has been shown to wear a red sweater. In "Cartman Gets an Anal Probe", she was seen wearing a green jacket, tan pants, and dark blue mittens, while in "Weight Gain 4000", her jacket and mittens were pink, with her jacket being a darker shade than her mittens. She also wore the aforementioned outfit in "Pinkeye". In the episode "Chickenlover", she was briefly shown wearing a blue jacket in a scene.
Bebe wears a short-sleeved, ankle-length, pink nightgown with white trimming around the cuffs and collar at bedtime, as shown in "Bebe's Boobs Destroy Society" and "Marjorine". When dressed as a whore in "Stupid Spoiled Whore Video Playset", she wears a fluffy white shawl, a fluffy white brazier, and a red miniskirt (which only comes to about her groin) which has a white buckle with a star in the middle of it. She also wore pink hair extensions drooping out of her hair, eye-liner, and blush. Bebe was also seen wearing a heavy amount of makeup in "How to Eat with Your Butt".
Bebe is usually a friendly person, and is seen hanging out with other characters, mainly the other girls in school. However, she has had rocky relations with the boy students.
In "Bebe's Boobs Destroy Society", she attracted unwanted attention from the boys and wanted them to appreciate her for her intelligence and aspirations rather than superficial traits such as her breasts.
Bebe also has an interest in makeup and fashion. In "Tom's Rhinoplasty", Bebe helped make over Wendy so that she could impress Stan again, and she was shown wearing a heavy amount of makeup for her school photo in "How To Eat With Your Butt". In "The Fractured But Whole", Bebe helps you with your outfit, commenting on how you need help with it. If you wear one of her costume designs, she excitedly takes a selfie with you.
Bebe is very much a trend follower, unlike her best friend Wendy. She jumped on the bandwagon of being a stupid spoiled whore when Paris Hilton came to town, and joined everybody in the new photoshop craze, where she photoshopped her picture to the point where it didn't look much like her at all. This could possibly imply she has some insecurities about her appearance, as she was also the first to snap back when Wendy commented on the other girls' flaws in "The Hobbit".
She can be emotional, crying over Heidi Turner quitting Twitter in "Skank Hunt". She is also shown to have a quick temper. Despite being generally nice, she has a mean streak and can be quite tactless. This is shown when she made fun of Heidi for dating Eric Cartman in "Doubling Down", which upset Heidi and caused her to go back to him at the end of the episode. She also made fun of Marjorine in "Marjorine", but felt guilty about that soon after and helped give Marjorine a makeover.
Bebe also has a Machiavellian personality; in "The List", she, Lola, Jenny Simons, and (to an extent) Red, had altered a list their Sunshine Community made rating the 4th grade boys based on how cute they are. In that sense, Bebe betrayed over half the 4th grade class for shoes. The list placed Kyle Broflovski at the bottom, destroying his self-esteem, driving him psychotic, to the point of attempting to burn down the school. When Stan teamed up with Wendy to investigate the list and confronted Kyle with the results, Bebe pulled out a gun. The police showed up and Wendy attacked Bebe. While struggling, Bebe accidentally pulled the trigger on Wendy, however, she missed, instead hitting and killing Kenny through a wall while he was eating dinner with his family.
