They called it quits earlier this year and now she says she feels like herself again.
In an Instagram post, the mum-of-three wrote: “Finally started to regain my energy 10 months after quitting IVF. For anyone going through this, it’s getting better!
She shared the post alongside a photo of herself on a treadmill, suggesting she feels ready to exercise again.
