Socialite Paris Hilton is so broody, she's set herself a baby deadline - she wants to start a family with boyfriend Benji Madden in 2009.

The hotel heiress has been dating the Good Charlotte rocker for three months, but already has marriage and babies on her mind.

And although she insists she is not currently pregnant, Hilton admits she hopes to be with child in 12 months' time.

She tells Britain's Heat magazine, "I do want a baby. Pretty soon. Not yet because I'm so busy, but next year."

Hilton's close friend and Simple Life co-star Nicole Richie gave birth to her first child - with Benji's twin brother Joel Madden - in January.
