The hair and make-up artist wedded her boyfriend of less than a year, Max Parker, in a small Scientology ceremony at London's upmarket Dorchester Hotel last month.
Her father Tom Cruise is said to have funded the 22-year-old's intimate nuptials, and there are conflicting reports as to whether he was there.
Nicole Kidman was not invited to her daughter Bella's wedding, even though she was staying nearby, as it has been claimed.
But Kidman was not on the guest list and, according to Page Six, didn't even know her adopted daughter was tying the knot - even though she was in London preparing for her appearance on stage in the West End.
They claimed the ceremony on September the 18 had been organised so Cruise could attend, as he was in Europe at the time.
Kidman is currently starring in Photograph 51 at the Noel Coward Theatre.
Initial reports suggested the couple didn't want either sets of parents to attend. But there was a suggestion the Mission Impossible star was there to give his blessings.
Only a small group of close friends were present for the wedding, with Bella's brother Connor also not attending in a bid to keep the wedding out of the limelight.
Bella, 22, and her IT consultant boyfriend exchanged vows in one of the five-star establishment's function rooms.
