Little Mix singer Jesy Nelson has reportedly split from her longtime love, fiancé Zion Foster, just weeks after revealing that her 8-month-old twins are battling a severe form of muscle disease. Nelson, 34, and Foster have gone their separate ways after four years together, but remain friends and coparents, The Sun reported on Monday, January 19. The couple got engaged in September 2025, just four months after Nelson welcomed their twin daughters, Story and Ocean. Us Weekly has reached out to Nelson's representatives for comment.
