KEY POINTS:
Joel Madden has revealed he is set to propose to girlfriend Nicole Richie after letting slip his plans on US TV.
The Good Charlotte frontman let slip his plans to pop the question during an interview on US TV show Live! when host Regis Philbin questioned him about his love life.
Regis said: "I hear you're going to present Nicole with a little engagement ring or something?"
Joel, who was on stage with his band ready to perform, replied: "Well I had been hoping it would be a surprise but I guess it's not now."
Nicole is four months pregnant with the couple's first baby, and Joel says he has been reading guidebooks to help him prepare to be a good dad.
He said: "I've been looking at books to help prepare me for when the baby comes. So far, I've read What to Expect When You're Expecting, The Expectant Father and Baby Signs."
Last week, Nicole said she was "desperate to be someone my child will look up to".
Joel and Nicole, who is set to begin her four-day prison sentence for DUI (driving under the influence) on September 28, have been an item for more than six months.
