You're 45 today, Jen. Take a trip down memory lane with us and look back through your life story...
You knew you wanted to become an actress after seeing the play 'Children Of A Lesser God' on Broadway. You started acting at the age of 11 when you joined the Rudolf Steiner School's drama club. Little did you know how famous you'd become... Pic: Pacific Coast News
It didn't help that two of the TV shows you got roles in - 1990's 'Ferris Bueller' and 'Molloy' - were cancelled during their first series. After 'The Edge' fell through too, you thought you'd never become an actress.
Two years on, and you were still finding it hard to break through. 1992's 'The Edge' never took off, and so did 'Muddling Through'. You told NBC's head of entertainment, Warren Littlefield, that you were worried about it ever happening for you at a petrol station. He told you to persevere. He was right! Picture: Photoshot
You originally auditioned for the role of Monica Geller, but you knew Rachel was the role for you. This was your big break! Finally! Warren Littlefield helped to get you cast. The rest, as they say, is history!
When the first series aired in 1994, 'Friends' was an instant hit. We adored you as the ditsy-but-loveable Rachel, Matt LeBlanc as the hapless actor Joey Tribbiani, Lisa Kudrow as the eccentric singer Phoebe Buffay, Courteney Cox as clean freak Monica Geller, and of course David Schwimmer as your on-off love interest, Ross Geller. It ran for ten hugely successful years and changed TV forever. We can all still quote along!
Sure, you don't actually like 'The Rachel' (you told Allure it was "the worst haircut [you've] ever seen"), but it's a testament to your status as a style icon that millions of people copied this chunky, layered style - and still do to this day!
You started dating Tate Donovan in November 2005, and got engaged the next year. It didn't work out, though, and you split not too long after - but not before he'd made a few cameos as Joshua on 'Friends'!
Having met Brad two years earlier, you tied the knot in a private ceremony in Malibu, California. You were Hollywood's golden couple, so it came as a surprise to us all when you split and then divorced in October 2005. Then again, some things just aren't meant to be!
You were given the coveted Outstanding Lead Actress in a Comedy Series at the Emmys 14 years ago, and your trophy cabinet has been further filled by People's Choice Awards and Golden Globes over the years.
It could have worked - you both have a great sense of humour - but ultimately you split in November 2006 after a year together. Ironically, you'd filmed 'The Break-Up' together...
By the mid-noughties, you'd been making $1 million per episode on 'Friends' and starred in huge hit films such as 'Along Came Polly', 'Bruce Almighty' and 'Marley & Me'. You're one of the most famous women on the planet.
Jennifer Aniston made it! We probably don't need to remind you how delighted you were on the day: "[This] probably wasn't even a dream, it was one of my wildest dreams. I don't think that I ever even thought that this would be here, this day. So I am utterly humbled and grateful."
You started dating in February 2008, and broke up a couple of times before finally calling it a day in March 2009. Nonetheless, your star had never been bigger.
That is quite an accolade, but we can see why. In their words: "Other sex symbols drift toward one-dimensionality, becoming flat icons in the process, but throughout her career Aniston has remained sexy, funny, and unmistakably real." You're now 45, and you're as hot as you've ever been.
You started dating in May 2011, and announced your engagement in August the following year. Could 2014 be the year you tie the knot? We've got our fingers crossed...
