The assailants took two laptops, which officers believe they will try to sell. They walked in off the street after pushing open a faulty communal door at her block near Hyde Park and forced open the door to her home.
Two other homes in that block have been robbed within a week.
"Keira is mortified to think anyone has been rummaging around her personal stuff," claims police. "She feels violated and doesn't know if she wants to return to the flat."
At least police don't believe she was targeted due to her fame.
"There's been a problem with the external communal door," said a builder working on the block's renovation. "It keeps sticking and you can push it open. I think the problem has been reported to the owners of the building but not fixed."
There are no suspects in the robbery.
