Her fourth album Rollerskating was released in late 2006. 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. It's Bertine as you know and love her, but with a new even more addictive sting in her tail." Lead single "Fake Your Beauty" was a radio hit and reached the top spot in the Norwegian charts. Its follow-up "Ah-Ah" was remixed on release and was a sizeable hit. Zetlitz released her fifth album My Italian Greyhound in September 2006. She described the album as "like its namesake: elegant, humorous, fit and well scented - with a charming hint of neurosis."
Zetlitz gave birth to her first child in 2007 and temporarily retired from show-business to become a full-time mother. Later that year she released the greatest hits album In My Mind 1997–2007 the Best of Bertine Zetlitz, which featured two new songs. She released her sixth studio album Electric Feet on 16 March 2012.
