Jennifer "Jen" Johnson is a houseguest from Big Brother 8. Jen was the seventh person evicted from the season and placed 8th, becoming the second member of the jury. Jen was known for being frequently tormented by Dick Donato's insults, her rivalry with Daniele Donato, not being liked by many of her fellow HouseGuests, and frequently talking about herself. She is also known for her meltdown upon seeing her memory wall photo, which she dubbed as "the worst picture I've ever taken". She is also known for wearing shirts that said puns about her nickname (ex: I'm a "Jenius").
Soon after Big Brother 8, Jen began to date her fellow houseguest Nick Starcevic (who had disliked Jen and was in a showmance with Daniele Donato during that season). They are no longer together.
Jen is the first houseguest to violate a food restriction. For doing so, she received a penalty vote. (She had been nominated for eviction that week.)
Originally, Jen was given a penalty nomination, which would have been effective the following week in the event that she was not evicted. This was changed to a penalty vote after several other HouseGuests complained that it unfairly gave them an incentive to vote to evict Jameka Cameron, the other nominee for that week.
