[1] During their hiatus, Mölling released a solo album, Unexpected (2004), which produced the top ten singles "Unnatural Blonde" and "Tell Me", and became a judge on the fourth season of Popstars.

The following year, she became a presenter and actress in several short-living television shows on Sat.1, Das Vierte, and VIVA Germany before serving as a judge on Die singende Firma.

In 2010, Mölling made her stage debut in the musical Vom Geist der Weihnacht, which led her to parts in productions such as Joseph and the Amazing Technicolor Dreamcoat and Cabaret.

For starring as Eliza Doolittle in the 2016 Bad Hersfeld revival of the musical My Fair Lady, she won the Audience Award for Favorite Actress.

She earned a position in the top 30 finalists and immediately travelled to Mallorca, Spain to join her competitors for a workshop, where she made it to the final 10 on the show despite her struggles with dancing choreographies.

During a special episode in November 2000, jury member Moslener eventually disclosed that Sandy was chosen to become part of the final five-member girl group No Angels.

With the final five members of the band in place, Popstars continued tracking the development and struggles of the group who left homes to move into a shared flat near Munich, Bavaria.

[1] A strong opponent of the disbandment of No Angels, Mölling, who felt less exhausted than her former bandmates, launched her solo career only months after the group's final concert.

[6] After a few hosting jobs and a sudden label change Sandy released her minor succeeded second album, Frame of Mind (#53), in May 2006 via Starwatch Music.

Sandy has also presented three television programmes on two different German networks, including Autsch TV on Das Vierte and both Du bist... and Damenwahl on the music channel VIVA.
