Jesy Nelson is engaged to her boyfriend Zion Foster. The former Little Mix star took to Instagram on Friday to reveal that she was engaged to the musician, who is the father of her twins. "Just got engaged to my best friend," she wrote in the caption, with ring and emotional face emojis, alongside a photo presumably taken just after the proposal, which took place at a beach at sunset. In the snap, Jesy flaunts her new engagement ring as Zion kisses her cheek while they stand on a blanket on the golden sand. In a follow-up image, the 34-year-old shared a close-up look at the new diamond sparkler on her ring finger. The couple was flooded with congratulatory comments from fans and friends, with fellow X Factor alumni Ella Henderson writing, "Awww congrats gorgeous girly! You deserve the universe." Jesy and Zion also shared the announcement post on their respective Instagram Stories, adding Truly by Lionel Richie as the audio. The rapper also wrote, "God is the greatest (heart emoji) the luckiest man." Jesy began dating Zion in 2022, and they became parents to twin daughters Ocean and Story earlier this year. The twins were born prematurely at 31 weeks in May because they were suffering from twin-to-twin transfusion syndrome (TTTS), a rare pregnancy condition that threatened their lives. After spending several weeks in neonatal care, Jesy and Zion brought their girls home in June. Jesy is currently working on the six-part Prime Video documentary series, Jesy Nelson: Life After Little Mix, which will chronicle the high-risk pregnancy, her new life as a mother, and what she's been up to since quitting Little Mix in 2020. A release date has yet to be announced.
