The 48-year-old actress posted a string of photos to social media where she appears to have an ageless appearance and fuller lips.
Worried fans have left comments quizzing the star on her changing appearance, asking 'what happened to your face?'
Fans continued to post comments about her changing looks, with some accusing her of having Botox and plastic surgery.
One commented: 'So sad for you, your face is so changed.'
'No like your new face' another said.
While a third wrote: 'What happened to your face Catherine?'
A fourth posted: 'Yet another celebrity with too much money - Catherine did not need plastic surgery and now she has had so much she is hardly recognisable.'
