‘Jesy Nelson: Life After Little Mix’ streams Feb. 13 on Prime Video. In the trailer, the singer, who left Little Mix in 2020, addresses her exit from the group. Plus, she emotionally documents her prenancy with twin girls, which was full of complications. Her daughters have since been diagnosed with Spinal Muscular Atrophy Type 1, a rare genetic condition that causes progressive muscle weakness affecting movement, swallowing and breathing.
