Barbie as the Princess and the Pauper

Barbie as The Princess and the Pauper is the fourth in the 2000's Barbie film series and is billed as the first ever Barbie Musical.

It stars Barbie as both Anneliese and Erika, a princess and a peasant. After a chance meeting, the two become quick friends due to their similarities. However, with the kingdom's finances falling, Anneliese is engaged to Dominick, the king of a neighbouring kingdom. When the queen's scheming advisor arranges for Anneliese to be kidnapped so the marriage to King Dominick will not go through, Anneliese's tutor Julian arranges for Erika to replace Anneliese until the real princess is found.
