She said: "That was a tough road for me as we both came from being single parents for a while and then suddenly then having to live with someone with a different parenting style to you.

"That is a recipe for struggle and for stress and surrender and growth are the only options if you want to stay together. It was not an easy immediate thing by any stretch of the imagination but I think slowly you start to learn how to truly compromise."

The mother-of-two continued: "Nobody gives you a handbook in being a mom and you definitely don't get a handbook in being a stepmom.

"And same with being a stepdad. It's something that people don't talk about and it's probably one of the hardest roles that I've taken on and I'm still learning how to be a better one.

"It's not an easy situation but I would say my heart grew ten times the size it was. You really have to open your heart and open your mind, and your flexibility is imperative when it comes to dealing with a blended family."
