Jesy Nelson’s new boyfriend has publicly piled into the bitter row with her ex — and the father of her twin daughters.

According to The Sun and matching Friday coverage, landscape gardener Ben Davies hit back at rapper Zion Foster after Zion posted a new track addressing their split and co-parenting of 17-month-old Ocean and Story, who live with Spinal Muscular Atrophy Type 1. Zion captioned the Instagram drop “first and last time saying my peace,” rapping about a “bleeding” heart, calling a lawyer, and claiming social media does not show the full story.

Davies answered in the comments, rejecting any suggestion Zion is being blocked from seeing the girls. “No one’s stopped you seeing the girls, you just couldn’t be a***d or too busy writing poems making money off them,” he wrote, challenging Zion to show recent messages checking in on the twins. Zion later switched comments off on the post.

The flare-up lands after months of tension. Jesy, 35, and Zion split earlier this year after the SMA diagnosis; both have moved on — Jesy hard-launched Davies around the National Television Awards, while Zion went public with a new partner known as Sav and faced “deadbeat dad” jibes he dismissed as people judging from “15 seconds” of his life. Jesy has previously liked social posts that dig at absent fathers, while stressing her priority is the girls.

Neither Jesy nor Zion issued a joint statement in the Friday reports. The public facts for now are the song, Davies’ comment, and a co-parenting dispute playing out in plain sight.
