Jenni Jones-Brown is a pre-made Sim who lives in the mysterious town of Twinbrook. 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. Her parents do not get along well.
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.
She takes her surname from both of her parents. As they both have double-barrelled surnames, she uses the last of each - Jones from Lenny Smith-Jones and Brown from Renee William-Brown.
Jenni is very pretty, too, and appears to take after her mother in looks.
