Courteney Cox is one of several celebrities that regularly make us question whether they have an ageing portrait locked in their attic. Like Jennifer Lopez, Paul Rudd, and Gwen Stefani, the erstwhile Friends star has either won the genetic lottery, or lives by a spartan skin and exercise routine. But if you have a gander at her most recent Instagram video, you're more likely to assume that her ripped abs are a result of some good old hard graft.

The 55-year-old took to Instagram yesterday to share a gravity-defying video of her hanging out by the pool. The clip sees her step out of the pool from a big splash, put on some sunglasses and a cover-up, and grab a refreshing drink - but this all happens in reverse.

What had us more spellbound, however, was her physique - I mean, she looks amazing!

Cox refers to Missy Elliot's Work It in the caption, which reads "Oh so now I finally get what @missymisdemeanorelliott meant by put your thing down, flip it, and reverse it....only took me ten years."

And her celebrity friends just loved it. "This is epic," wrote Kaley Cuoco, while Erin Foster added "I don’t know what’s cooler, this video or how good your body looks."

In related news, the actress recently revealed that she had her fillers dissolved, admitting that she "didn't look like [herself]".

"I would say it’s a common thing you go through as you age, especially in Hollywood," the 54-year-old disclosed when speaking to PEOPLE. "You have to accept getting older, and that’s something that I had a hard time doing."

The actress - who is now the new face of L'Oréal Paris' Super Preference #OWNINGIT campaign - added that she started getting the injectable fillers because she "wasn't pleased with myself and the way I looked."

“[I tried] to keep up with time in a way that was anything other than maintenance. I didn’t realise it until one day I kind of stepped back and went, ‘Oh shit. I don’t look like myself.'”

But now, after getting her fillers dissolved, Cox has found that she's more confident than ever;

"So now I just embrace who I am and getting older with what God gave me, not what I was trying to change. I kind of own everything. And the things that I am not as comfortable with myself, they’re things that I continue to work on to grow and change. I am at a stage of my life where it’s very easy to be comfortable with who I am and who I’ve become and who I strive to be."

Good on you, Courteney!
