Jennifer Aniston has been a fixture on our TV and movie screens for decades, ever since she made her big debut on Friends in 1994.
Since then, the now 50-year-old has starred in dozens of movies, including the newly-released The Morning Show, curating an astronomical net worth estimated to be about US$200 million.
It's no secret that Jen looks fantastic, thanks to an intense diet and fitness regimen, but what about any tweakments she's had to her face?
Well, she has admitted to having work done on her nose.
"It's funny. I had [a deviated septum] fixed – best thing I ever did," she told People in 2007. "I slept like a baby for the first time in years."
When asked about the rumours she's had other work done, including a breast augmentation, Jen denied the claims.
"As far as all the other [rumours], as boring as it sounds, it's still mine. All of it. Still mine," she said of the boob job rumours.
"Short of letting everybody have a feel, I don't know what else to do," she continued. "I really am pretty happy with what God gave me."
But she is a fan of a good in-salon skin treatment.
"I became obsessed with laser porn. I did this thing called like, a peel," she revealed on Late Night with Conan O'Brien.
"It's extremely intense – you don't realise you look like a battered burn victim for a week – and then it [the dead skin on your face] just kind of falls off."
Dermatologist surgeon Dr Daniel Lanzer says Jen "looks great" for 50, and that's either down to impeccable genetics, or a little help from a few cosmetic surgical treatments.
"She's got very nice, well-formed cheeks. There's lots of different ways people enhance their cheek volume when they're older," Dr Lanzer said, suggesting Jen could have undergone a range of surgical treatments.
"One millilitre of filler takes a few minutes to inject. Another thing that's very common these days is take a bit of fat from somewhere else in the body and inject it into the face. That gives you nice volume. And sometimes when people get older they get cheek implants , but I don't think Jen has had those," he said.
"They [her cheeks] look natural, but it's always possible that she could have had either of those procedures."
Dr Lanzer also suggested that Jen might have had some work done to remove her smile lines, as well as shape her jawline.
"She has a lovely deep smile, but one of the things about a deep smiles is it that it causes a crease on the nasal labial fold. She still has that fold, but there are minimal lines there," Dr Lanzer said.
"As people age, the first thing they lose is that very sharp jawline. She still has a very sharp jawline .. that could be that she has wonderful genetics or she might have had some sort of lift, perhaps a form of radio frequency that causes tightening," he said.

Jen's impeccable skin texture is probably due to her fantastic at-home skincare regimen, combined with top-notch in-salon treatments, Dr Lanzer said.
His salon offers many treatments that improve skin texture, that are hugely popular with older female clients.
"Skin texture treatments are extremely popular and common. Good creams and products with high concentrations of vitamin A and vitamin C and AHAs can keep ageing at bay," he said.
"There are also a lot of refreshing lasers we use now, so things like DermaSweep and Derma Fraxel and deeper lasers ... they're things you can do to maintain the skin texture."
