Jessica Biel is not ready to have children.

The 29-year-old actress - who is in a relationship with Justin Timberlake - is keen to start a family one day, but it isn't something she is currently thinking about.

She said: "I'd like to have children one day but I don't have any timetable for that.

"It's not something I'm thinking about right now."

The 'New Year's Eve' star recently admitted she is in no hurry to get married.

She said: "I was never one of those girls who dreamt of my wedding and my Prince Charming. To p**s off my mom, I used to say, 'I'm never having kids, and I'm going to be a fabulously rich old maid living in a house with cute butlers and dogs.' "

Although Jessica refuses to talk about her relationship with Justin, she has insisted actors don't just date fellow stars for publicity.

She said: "I think those (actors) are the people you meet and so it just kind of happens. Let me tell you: It never happens on purpose."
