Jenni Jones-Brown is a pre-created Sim who lives in Twinbrook, the neighbourhood that ships with The Sims 3: Ambitions. At the beginning of the game, she lives with her recently divorced parents, Renee William-Brown and Lenny Smith-Jones, at 4 Poker Flats Drive, as part of the Jones-Brown family. Her parents do not get along well, and impressively still live in the same house as each other.
She is also romantically involved with Goodwin Goode, a young Sim who lives in the Goode and Bad household. Shortly after the game starts, Jenni discovers that she is pregnant with his child and she is affraid of what people might be think about that and about her parents' reputation.
She takes her surname from both of her parents. As they both have double-barrelled surnames, she uses the last part of each - Jones from Lenny Smith-Jones and Brown from Renee William-Brown.
Jenni appears to have gotten the majority of her genetics from her mother. However, she does not follow her mother's career path and is employed as a Spa Receptionist at Level 2. Jenni has only 2 skill points in Charisma.
