Kerr, 27, who shot to international fame as a Victoria's Secret lingerie model, and Bloom, 33, star of the "Pirates of the Caribbean" and "The Lord of the Rings" movies, began dating in 2007 and have frequently denied rumors of an impending wedding.
But the couple's publicists last month confirmed that this time the reports were true and they were engaged.
Australian store David Jones, for which Kerr is an ambassador, confirmed the wedding in a statement released to the Australian media on Friday, that said Kerr had canceled her appearance at the store's upcoming spring/summer fashion launch.
"We have been trying to plan this for some time and unfortunately the only window of opportunity for our honeymoon fell at the same time as the David Jones fashion launch," Kerr said in the statement.
"David Jones very graciously released me during this period so we could celebrate an intimate ceremony and honeymoon together."
Kerr, who was raised in the country town of Gunnedah in the state of New South Wales, was ranked ninth on the Forbes' Top 10 Earning Models list this year after earning an estimated $4 million in the past 12 months.
The mayor of Gunnedah, Adam Marshall, offered the star couple a street parade and use of the town's award-winning brass band if they chose to marry in his town, but it appeared the couple opted instead for a small Los Angeles wedding.
