Regen Jamison is a character in The Barbie Diaries, and is a friend of Raquelle and Dawn. She is a popular, but two-faced, teenage girl who becomes friends with Barbie so they can gossip. After hearing about her undercover news story, however, Regen and Dawn stopped talking to Barbie and thought that Barbie herself was a hypocrite for pretending to be friends with them. Regen and Dawn return to hanging out with Raquelle afterwards. By the end of the film, they have abandoned Raquelle and talk to Tia about methods of organizing clothing.
