Hollywood's sweetheart will mark a half century since her birth on February 11, and the former Friends star has been vocal about how much she's looking forward to it.
In an interview with US Weekly, Jen said: "I don't think life stops after 50 - if anything, it gets more and more exciting."
The A-list actress went on to say she dislikes the way aging is discussed, particularly in the entertainment industry, and believes we should celebrate the process with honour and respect.
After cementing her name in the Hollywood hall of fame as Rachel Green on Friends, Jen went from professional strength to strength appearing in hit movies including Horrible Bosses, The Bounty Hunter, Bruce Almighty and We're the Millers.
Her recent project, the Netflix feature film Dumplin', will be followed by a further two Netflix movies as well as a 10-part TV comedy with Reese Witherspoon and Steve Carrell.
According to Forbes, the Los Angeles native is worth an estimated $280 million AUD and has consistently ranked on the list of 100 Most Powerful Actresses in Hollywood for the past decade.
But despite her incredible success, movie star looks and flawless physique, life hasn't always been straight forward for Jennifer.
The California girl has endured her fair share of heartache and personal sadness in the sharp glare of the public eye, trials which started with her very public divorce from Brad Pitt in 2005.
A decade later the world wished Jen-An well on her relationship with Justin Theroux but their seemingly happily ever after crumbled in another divorce in 2017.
Jennifer has spoken candidly about her romance woes, slamming the media for repeatedly shaming her single status.
"Why are we only looking at women through this particular lens? Maybe my purpose isn't to procreate - maybe I have other things I'm supposed to do."
A source close to Jen told US Weekly she "isn't looking back" and that she truly does believe "life gets better with age".
One constant in Jennifer's life has always been her solid squad of female friends, consistently led by her Friends co-star Courteney Cox and industry elites like Selena Gomez.
This legion of supportive women often gather at Aniston's Bel-Air mansion for what she describes as "Sunday Fundays" where "it's all sweatpants, jeans and flip-flops".
We're sure her girl gang will ring in Jen's big 5-0 in truly spectacular style next week!
