In extracts from her new autobiography published in the News of the World, the I'm A Celebrity winner revealed that she initially didn't want to be a mother, meaning she didn't bond with son Zach straight away.
"I hated every second of my long, long labour," she admitted."I didn't feel motherly. I felt so hopeless, like I was nothing. I didn't want a baby. I really didn't. I went on crying and crying. I cried my eyes out for days. I really didn't want this to be happening to me.
"Apparently, women forget how bad labour is once it's over. Well, I'm telling you now, I am never going to forget it. Never! No one said, 'It's the most horrendous thing you will ever go through and you will feel like you're going to die'.
"I felt totally disconnected, as if I was outside of my body. My thoughts and feelings didn't seem to be part of me, which I've since learned is a symptom of postnatal depression. I felt I was a hopeless mother."
She also claimed that fellow X Factor finalist Olly Murs was jealous of her boyfriend Aaron Barham, which put a strain on their friendship. "I didn't fancy him," she said. "He got a bit funny, as Aaron came to see me quite a few times [on tour]." The pair have since made up.
Solomon is currently being sued by her former management company.
