She has always had a stunning, radiant complexion which makes her appear much younger than her 43 years.
But as pictures emerged of Jennifer Aniston on the set of her latest movie yesterday, the actress sparked concern with what appeared to be a overly plumped up face.
The images of Jennifer caused fans to take to the internet to comment on the actress' 'pillow face' - a common term used for women who have used too much filler in their face.
Another pillow face victim? Jennifer Aniston yesterday sparked concern with her plumped-up complexion on the set of her new movie We're The Millers. Many readers commented that she looked drastically different to the way she used to look (right)
One MailOnline reader wrote: 'Too much filler, she's got that fat faced over fillered look, that is so popular in Hollywood, for some reason. She used to have really nice cheekbones, now she's got a pudgy, filler face.'
And another added: 'I always admired her for being fresh-faced, but now it looks like she's developing that pillow-faced look that seems to go with meddling with your face. If it ain't broke, don't fix it!'
Jennifer has admitted to having a little cosmetic help in the past, telling US talk show host Conan O'Brien earlier this year that she previously had a chemical peel to help her stay looking young.

She said: 'I became obsessed with laser porn. I did this thing called like, a peel. It's extremely intense – you don't realise you look like a battered burn victim for a week – and then the dead skin on your face just kind of falls off.'
Jennifer was yesterday seen shooting new movie We're The Millers, in which she stars as a prostitute, in Wilmington, North Carolina.
The actress sported a pair of Daisy Dukes that were ripped and frayed, paired with a revealing white vest top.

The star wore minimal make-up and accessorised with just a simple pendant necklace and single beaded bracelet, as well as gold earrings.
While the outfit may have been a bit too saucy no doubt Jennifer would have preferred it to the drab ensemble she switched into later in the day.
She was later seen sporting a much more modest get-up in the form of a red and white checked top and khaki trousers.
We're The Millers follows Jason Sudeikis's pot dealer as he creates a fake family in order to smuggle 1,000 pounds of pot across America.
Jennifer plays a prostitute hired to play Jason' wife and co-stars alongside Emma Roberts and Parks and Recreation star Kathryn Hahn.
