Nicole and Joel are reportedly planning to honeymoon in Australia, where they conceived their unborn baby. The couple conceived a child during a trip Down Under earlier this year, when they spent time there around the Australian MTV Awards. And insiders claim they’re hoping to go back following a top secret wedding next month. The aides insist the new Mr. and Mrs. Madden will spend quality time together before the rocker’s band Good Charlotte plays a string of Australian concerts in mid-October. A source says, “They fell in love with Australia when they were there in April and they can’t wait to go back and honeymoon there.”
