Nicole Safft (born 19 November 1975), known professionally as Rollergirl, is a German singer with a number of successful tracks such as "Dear Jessie" (a loose cover of the Madonna song) and "Luv U More", a cover of the Sunscreem song.

Safft was discovered by German producer Alex Christensen on Mallorca and signed up for auditions.

The pseudonym Rollergirl was taken from Heather Graham's role as a naive young porn starlet in the film Boogie Nights.

"Geisha Dreams" (2002) was Rollergirl's last release[1] before she retired to focus on her private life, including Christensen and their son, born in 2003.

Safft has also appeared with Daniel Hartwig as co-presenter of the German television channel RTL 2's The Dome and Megaman 2002.
