In 2009, Hill was chosen as Jackson's duet partner for the song "I Just Can't Stop Loving You" during his This Is It concert tour. After Jackson's death in 2009, she, along with the rest of the This Is It cast members, performed at Jackson's memorial service and attracted global attention when she sang the lead on the song "Heal the World". Hill's rise to fame is briefly recounted in 20 Feet from Stardom, a documentary film that tells the untold story of the backup singers behind some of the "greatest musical legends of the 21st century"...
