Tom Cruise's children with Nicole Kidman call his new wife Katie Holmes 'mom'.
Katie, 29, revealed she has such a bond with Isabella, and 12-year-old Connor - who both live with Katie and Tom in Los Angeles - they refer to her by the parental term, even though they call their adoptive mother Nicole by her first name.

She said: "Tom is a great father and husband and Connor and Bella are incredible, really smart and kind. They call me 'mom.'"
Nicole - who primarily lives in Tennessee with her husband Keith Urban - is said to be furious and has banned her children from calling Katie 'mom'.
A source said: "Nicole was anxious to make it very clear that she is Connor's and Bella's mother. They may not live with her but no one can take that away from her."
