Peaches Geldof has said becoming a mother was like a rebirth for her, and made her want to be a good person.
The 23-year-old former wild child daughter of Sir Bob Geldof and Paula Yates opened up to Elle magazine about the difficulties she faced from her parent's divorce followed by the death of her mother when she was just 11.
Peaches is now a mother to seven-month-old son Astala and married his father, rocker Tom Cohen, in September.
She told the magazine: "For so much of my life I felt old and jaded, even though I was a teenager. Being with Tom, having Astala, a big thing for me is I actually feel young.
"His birth was like a rebirth for me, and I honestly never thought anything in my life would ever be good. I'm obsessed with getting it right. The second I held him it was like this missing piece of my life being put into place; everything started to heal."
Peaches previously married rock musician Max Drummey in 2008 in a drive-in ceremony in Las Vegas after a 10-day romance, and divorced just six months later.
She revealed how being a parent had changed the meaning of marriage for her.
She said: "What I learned from my first marriage is the sanctity of it. I regret that I hurt my friend and I hurt myself because of it. If you do it wrong, you want to make sure you do it right the next time.
"The very worst thing that happened to me started with my parents' divorce; it really affected the rest of my life. Even if it's an archaic idea I want Astala to have a mummy and daddy together forever. It's a commitment. I want to be a good wife, a good mother, a good person."
