But the mother-of-three has remained strong, with the father of her first two children- Karl Dures- offering to raise baby Arabella despite their platonic relationship.
And now the 28-year-old has shared her first gorgeous picture of the blue eyed beauty, born in November.
The X Factor runner-up wrote alongside the shot: "Mummy and arabella being silly she makes me laugh so much her personality already blue eyed girl xxxx I don't like to post pics of her much but this was just too cute xxx".
Rebecca gave birth in October 2014, sharing the touching picture below.
Speaking to Hello about her relationship with Arabella's father- who admitted he already had a girlfriend on finding out she was pregnant, she confessed:
"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."
She is also mum to daughter Lillie May and son, Karl. Ferguson.
