Christie and Teresa Barbie Lyrics Follow

Teresa is a Mattel fashion doll who is marketed as one of Barbie's fictional friends. Teresa debuted in the "California Dream Teresa" doll in 1988 and since then, she has been Barbie's most frequently featured female companion in the toy line (next to Christie). As of 2006, Teresa has been one of Barbie's core friends in the Barbie brand along with Summer, Nikki and Raquelle.
In a trailer for the 2008 movie Barbie and the Diamond Castle, the narrator describes Teresa as Barbie's best friend. In the film itself, Barbie states that Teresa is officially her "best friend and sidekick". In Life in the Dreamhouse Barbie states that all girls Teresa, Nikki, Summer, Midge, Raquelle & Grace are all her 'BFFs'.
