American actress Courteney Cox has always been loved by fans for her acting talent and beauty.
The 51-year-old became even more famous after playing the roles of Gale Weathers in horror series Scream and Monica Geller on the iconic sitcom Friends.
Cox has always won praise for how she managed to maintain her good looks over the years... until now.
When she stepped out to the Amazon premiere screening for original drama series Hand Of God at the Ace Hotel in Los Angeles on Wednesday, the star shocked fans because she looked almost unrecognisable.
Her cheeks were puffy, her eyes were smaller than usual and she looked like she had aged a lot.
This has led to speculation as to whether she has used too much Botox.
