Four months later, Zion got down on one knee and the pair revealed they were engaged in an adorable post captioned: "Just got engaged to my best friend 🥹💍"

Why did Jesy Nelson and Zion Foster split?

Jesy confirmed their split and said it was because their "energy" had changed as they had to begin caring for their daughters' SMA diagnosis.

Speaking to the Daily Mail, Jesy shared: "We have been through such a traumatic experience and for us, our girls are our main priority and our main focus.

"We want to give them the most positive, happy and uplifting time and energy and because we have both been through such a traumatic experience, the energy wasn't right between us, which is understandable."

When their split was first reported, a source told the tabloids that Jesy "and Zion remain friends and are fully focused on their daughters".

They added: "They are fully united in co-parenting. Their priority continues to be the well-being of their daughters."

This comes after fans noticed that during her appearance on This Morning, Jesy was not wearing her engagement ring.
