Grammy winning R&B/hip-hop star and former Fugees frontwoman Lauryn Hill has called off her entire European tour, citing unspecified health issues, according to the Associated Press.

The summer trek would have been her comeback tour and marked her return to Europe after a two year absence since she was booed off a London stage for showing up two hours late.

Hill was to headline this year’s Stockholm Jazz Festival in Stockholm, SWE, on July 15 as well as perform on July 11 at the Montreux Jazz Festival in Montreaux, SWI. Shows in the Netherlands, Germany, Poland, Italy, France, Austria, and Greece were also canned. The singer previously headlined the Stockholm Jazz Festival in 2005.

The reclusive Hill last performed live in 2007 at a free concert at Wingate Field in the Crown Heights section of Brooklyn, NY. She was said to reportedly be working on new music.

Her 1998 debut solo album, “The Miseducation of Lauryn Hill,” won five out of 10 Grammy awards, including Album of the Year, making her the first female artist to win five Grammys in one night. Since that effort, she had not produced another full-length studio album, though she did release the live “MTV Unplugged No. 2.0” in 2002 to mixed reviews.
