In their joint interview, Alan’s girlfriend opened up about her bond with Sienna.
She said: “When I first got together with Alan and became a bigger part of Sienna’s life, my dad said, ‘This will be the making of you’.
“It’s tricky when you’ve gone from being a single girl with no one else to think about, to someone with a family.
“It’s the best thing in the world but it can be really daunting. I wouldn’t change it for the world.”
