Expectant parents Nicole Richie and Joel Madden will reportedly marry at Lionel Richie’s California estate next month before before flying to Australia for a romantic honeymoon-baby bump and all.

“They fell in love with Australia when they were there in April for the Australian MTV awards,” a music industry insider tells the tabs.

“They can’t wait to go back and honeymoon there.” Good Charlotte is touring Australia from October 9 to 17.
