In the episode The BoJack Horseman Show, set in 2007, Mr. Peanutbutter is noticeably jealous of Jessica's friendship with Justin Timberlake and she hints that she would want to marry him - in real life, Biel and Timberlake began dating in 2007 and would go on to marry in 2012.
It is unspecified when she and Mr. Peanutbutter first married, but in 2007, they went through an argument over one of Mr. Peanutbutter's offers, which ended in Jessica leaving him after Justin Timberlake was brought up.
Ten years later, in 2017, after Mr. Peanutbutter drops out of the election for the governor of California, with help from Katrina Peanutbutter, another ex wife of Mr. Peanutbutter, she runs for governor. She loses the election.
When married to Mr. Peanutbutter Jessica wore a black tunic with a rhinestone studded v-neck collar a pink long sleeve cardigan, and jeans. Her long brown hair was tied in a ponytail with long bangs framing her face.
When running for Governor she wore a burgundy pant suit, whit collared shirt, grey necktie, and her Ombre style brown hair down, and blue eye shadow.
Jessica is shown to be an exaggerated version of her real life counterpart. Jessica is shown to be a rude egoist who loves being in the public eye, having her picture taken, and reminding everyone, "I'm Jessica Biel." She also likes incorporating her last name into everyday speech. "UN-BEIL-EVABLE", or her perfume line BEILIST are examples of this this may have been a habit acquired from her current husband Justin Timberlake.
She is seen constantly putting down Mr. Peanutbutter for taking every offer that comes his way regardless of how much he enjoys being in them calling those roles beneath him. Yet, she keeps bragging about her own participation in critically reveled movies such as Stealth and Rules of Attraction, completely oblivious to their reception. Apparently, she was also 'told' I Now Pronounce You Chuck and Larry would be an important gay rights film.
She also enjoys leadership positions such as when she was running for governor of California or her role in Underground.
- Real life Jessica asked the writers to be harsh on her and make fun of her so that's how the animated Jessica was born. This also explains her role in Season 4.
- In 2007 Diane Nguyen didn't recognize her till she said she was "That girl from 7th Heaven who took her clothes off for that one magazine."
- She hates avocado.
