Weis was born the second daughter to Manju, an Indian interpreter and her German-Jewish father Helmut, a retired grammar school teacher.

The judges Alex Christensen, Noah Sow and Detlef Soost were impressed with her performance of Usher's song "You Make Me Wanna".

Weis earned a spot in the "recall" and "re-recall" (second and third round, respectively), and subsequently made it to the final eight of the show.

During a special episode in November 2001, jury member Soost disclosed that Weis was chosen to become part of the final group, later named Bro'Sis.

With the final six members of the band in place, Popstars continued tracking the development and struggles of Bro'Sis.
