Her third album, Sweet Injections, was released in 2003, helmed by electronic experts Howie B, Magnus Fiennes and Richard X (Sugababes, Rachel Stevens).

EMI describes the release as a "fascinating and unique blend of pulsing electro, classic Disco nouveaux, twisted pop melodies and good old fashioned catchy choruses.

Lead single "Fake Your Beauty" was a radio hit and reached the top spot in the Norwegian charts.

She described the album as "like its namesake: elegant, humorous, fit and well scented - with a charming hint of neurosis."

Later that year she released the greatest hits album In My Mind 1997–2007 the Best of Bertine Zetlitz, which featured two new songs.
