Sarah Harding doesn't feel ready to start a family with her boyfriend Mark Foster just yet, but would like to conceive her first child within three years.
Sarah Harding doesn't feel ''responsible enough'' to have children at the moment.
The former Girls Aloud star, 32, has been dating Mark Foster for the past 18 months, but she admits she's not ready to settle down and start a family with him just yet.
Speaking to Closer magazine, she said: ''I thought I wanted marriage but now I'm just taking it as it comes.
''I do want children one day but I certainly don't think I'm responsible enough at the moment.
''My mum was in her later 30s when she had me and I like to think I'll have kids by about 35.''
The blonde beauty recently admitted that she would like to have a big family eventually and is even considering adopting children like Angelina Jolie and Brad Pitt.
She said previously: ''I don't know if I could push out that many! I might do an Angelina Jolie and adopt a couple. I haven't thought that far ahead, to be honest.''
Sarah also believes her relationship with Mark is unlike any other romances she's had in the past because he's her best friend as well as her lover.
She explained: ''We met when we worked together at a pizza shop! He was a drum 'n' bass DJ and I used to go and watch him play. It's cool because he's my mate as well as my boyfriend. We were on and off for a few years back then and just drifted back together last year when he got in touch out of the blue. It must have been meant to be.''
