The recently single mum has allegedly been calling Suri “Sara” in public in an effort to help disguise her identity, a source told In Touch magazine.
The famous six-year-old has been in the public eye her whole life and is often snapped looking visibly upset with the constant media attention from the paparazzo.
“Everyone in the world knows Suri Cruise, so if Katie or a babysitter says ‘Suri’ people immediately look to find her”, the source said.
The actress was recently heard referring to her daughter as 'Sara' in front of her Dead Accounts co-stars.
The pint-sized celeb has also reportedly taken to the new nickname and was spotted at a Build-a-bear Workshop back in August requesting that her bear be called ‘Sara’.
The 33-year-old was awarded sole custody of Suri following her very public divorce from Tom Cruise in July.
The source says the extra security measure taken to keep Suri from the public eye is “no different to celebrities checking into hotels under a different name.”
