In 1990, Sabrina was the hostess of the daily morning TV show Ricomincio da 2 with Raffaella Carrà on Rai Due, and appeared on the popular music show Festivalbar with a new single called "Yeah Yeah". 1991 marked a turning point in Sabrina's career: she performed a duet with Italian singer Jo Squillo in singing "Siamo Donne", her first release in the Italian language. They performed together at 1991's Sanremo Music Festival to much acclaim.

Sabrina's third studio album, Over the Pop, was released that same year, and for the first time she was allowed to co-write and produce some of the songs. It was clear that Sabrina's will to mature as an artist were emerging, and this desire for independence led to conflict with her management. As a result, the album promotion was interrupted and only one more single, "Shadows of the Night", was released from the album.

A picture disc edition of Over the Pop was released later in 1991, now including "Siamo Donne'". Also on this version of the album an album version of "Yeah Yeah", was replaced by the remix version of this song.

"Yeah Yeah" was released as the first single from Sabrina's third album Over the Pop. The song reached #24 in Italy.

Then, "Siamo Donne" was released in January 1991 and was available only on a picture disc edition; it was Sabrina's first duet and her first release in the Italian language. This song reached #11 in Italy.
