Chelsea Roberts is one of the three tritagonists of the Barbie franchise, appearing as one of the deuteragonists of the Barbie and her Sisters franchise and the film series, and one of the two protagonists of Barbie and Chelsea: The Lost Birthday. She was originally known as Kelly Roberts and Shelley in Europe. In 2011, she was reinvented as Chelsea. The character is the youngest of Barbie's sisters and has appeared prominently in the late 2010/20s Barbie films.
Like her oldest sister Barbie Chelsea loves the color pink, enjoys strawberry shortcake and owns a pet dog. Being a 7-year-old, she is kind, loveable and innocent but tends to be more cheeky and gets into trouble more than her previous incarnation. Despite being a child, Chelsea is very smart for her age and enjoys pulling pranks.
