Speaking to Hello about her relationship with Arabella's dad - who admitted he already had a girlfriend when he found out Rebecca was pregnant - the singer said: "I was fuming when I found out, I was so angry. The way I was treated was wrong. I think some people think you're devastated because you want the man, but it's not that. It's devastating for a woman because it's a normal thing for your child to be wanted.

"I don't hold any hate towards him.

"He wasn't ready to be a dad and that's up to him. I'm not in his shoes and I can't force him. I'm happy with his decision now and I wish him and his partner well."

Last month, Rebecca - also mum to daughter Lillie May, nine, and son, Karl, seven, revealed the pressure she's received to lose her post-baby weight since having Arabella.

She said she's come under pressure to be like the ping-back celebrities who instantly slim down after having a baby, but she's refused to comply because she's 'happy in my own skin'.

In an interview with the Mirror, the singer said she isn't worried about losing the baby weight instantly.
Rebecca said: "I'm really happy in my own skin, it's other people who aren't happy.

"People say 'Oh, Becky don't you want to lose a few pounds', and I'm like 'I'm really content, I'm the happiest I've ever been'.

"It's funny how the world [perceives] how you should be after pregnancy now, they think you should snap back into shape especially if you're in the public eye.

"I say it's OK to enjoy your baby."
