Thania Garcia Jenni Rivera’s children have confirmed new music from the late Mexican music star is on the way, with a posthumous single called “Misión Cumplida” slated to arrive Nov. 2. The song is from a full 11-track album, slated for release on Dec. 9. Rivera’s children — Chiquis, Johnny, Jenicka, Mike, and Jacqie — spoke at length for the first time on their plans to release Jenni’s forthcoming album, which includes unreleased music, during Billboard’s “Children of Jenni Rivera” panel on Sept. 27. Johnny, the youngest sibling, appeared sporting a photo of his mother on his shirt, which he later revealed to be the cover art for “Misión Cumplida.”
