The ceremony is said to have been a mix of Christianity and Scientology, as Bella is reportedly a Scientologist and Max is not.
Tom Cruise and Nicole Kidman's adopted daughter, Bella Cruise reportedly got married in secret last month.
Bella is notoriously camera shy and the ceremony was so private that even her famous parents weren't there, in order to keep attention away.
Entertainment Tonight reports that Bella and boyfriend Max Parker's marriage took place at the luxurious Dorchester Hotel in London on September 18. Parker is a British IT specialist, whom Bella, 22, reportedly met earlier this year.
Kidman has been in London since July performing in the play Photograph 51 in the West End, and she reportedly did not miss her show the night of the wedding.
Kidman said to be overjoyed
The newlyweds are said to have booked the best suite in the hotel for their first night together as husband and wife, but said "I do" in one of the hotel's smaller function rooms in front of a small group of their closest friends.
Kidman, 48, is said to be "overjoyed" for her daughter, whom she and Cruise, 53, adopted along with their 20-year-old son Connor. Connor was also absent from the wedding.
Bella is reportedly a graduate of the Sassoon Academy, and working as a stylist in London. Four of her friends were said to have been bridesmaids. It's believed that she has already changed her last name to Parker.
