While the money rows are over, Martin Holmes is said to be upset at the pressure his daughter is under to lose weight in time for her wedding.
Determined to lose three stone in just over two months, she has hired fitness firm Buff Brides which has devised a weight-loss programme with Cruise. Sue Fleming of the company said: 'Katie can and will do it. She has great motivation.
'She loves her fiancÈ and was proud that Tom oversaw this programme.
'He told her he wanted her to be the most beautiful bride ever. She was in tears when he said that.'
There has been cynicism about Cruise's romance with Miss Holmes since the couple first became involved a year ago - when both were promoting movies.
The normally reserved actor attracted ridicule when he jumped up and down on the sofa on Oprah Winfrey's TV show and declared 'I'm in love. I'm in love'.
But a year on he has not stopped. Last week, in London for the premiere of Mission Impossible III, he told fans he loved Miss Holmes more than ever since they became parents.
