with Linn's sister Jenny seemed to indicate Linn's desire to return to the spotlight again, but Linn still remained hidden from the public. In October and November 2005, the band made appearances at a series of 15 concerts at the Night of the Proms in Belgium; as usual, Linn was "unable to attend", and only Jonas, Ulf, and Jenny made appearances at these concerts. During this time, Linn also recorded backing vocals for the track "High Life" in Jenny's secondary band, Arose; the song was released on their debut album in February 2006. In 2006, it was mentioned that Ace of Base had recorded six new songs featuring vocals by both Malin and Jenny. Some of these tracks later surfaced on the 2015 release Hidden Gems. Departure (2007) According to an interview given by Ulf Ekberg on 20 June 2006, Malin returned to University to study Judaism and would record vocals on the band's new album. However, on 30 November 2007, Ulf stated in an interview that Malin Berggren had left the band and she would not appear on the band's new album. The group had already been performing mostly without Linn as a trio for a solid decade before her departure. Bandmate and sister Jenny confirmed Linn's departure in the Danish press: "She hasn't been part of Ace of Base for several years," she stated in Se & Hør magazine. Ulf remarked: "She has no craving to be famous, she loved her fans, but the fame factor was not for her." The remaining band members promised Linn that they would never ask her to rejoin the band ever again. Linn's image was removed from most material on the band's official website but was reintroduced upon the release of Hidden Gems. Personal life Linn is multi-lingual: her primary language is Swedish, but she speaks fluent English and German; she also speaks Spanish, Russian and French. Other details of Linn's life, such as those of her life outside the band, are unknown to the public—whereas the other band members have been open about their relationships (Jonas and Jenny both have spouses, each with children, and Ulf has three children with his long-time girlfriend). As of 2015, Jonas confirmed he still sees Linn regularly and that she is enjoying a peaceful life with no interest in fame or returning to music.
