The actress has long been one of the last remaining holdouts of her A-list peers to have avoided social media.

Jennifer Aniston is Instagram official.

The actress and producer joined the platform Tuesday and posted her first photo — an epic Friends cast reunion photo alongside former co-stars Courteney Cox, Lisa Kudrow, Matthew Perry, Matt LeBlanc and David Schwimmer.

The pic, which comes just weeks after the NBC iconic comedy celebrated its 25th anniversary, nearly broke Instagram by briefly crashing her account. "Sorry this page isn't available," read an error note, which was quickly rectified by the platform — good news to her newly minted social media fans who praised Aniston's Instagram debut to the tune of 3 million likes by 11 a.m. PT.

Aniston, at 50, has long been one of the last remaining holdouts of her A-list peers to have avoided social media. Julia Roberts, Cox, Nicole Kidman, Reese Witherspoon, Charlize Theron, Cameron Diaz and many more all are on the photo and video sharing platform. But Aniston has never been shy about the reason why she's avoided it — until now. Just last month, the Emmy-winning actress told InStyle that she "worries about the damaging effects of social media on young people figuring out their identity."

"They're doing it through someone else's lens, which has been filtered and changed…and then it's 'like me, don't like me, did I get liked?' There's all this comparing and despairing," Aniston said in the cover story for the mag's Beauty Issue.

A few years prior, in a 2017 interview with Vogue, she likened social media to the tobacco industry: "It's hard enough being a kid growing up and becoming who you are and finding yourself but now you have social media and you've added this extra pressure of seeing if someone likes or doesn't like something you did. We're creating these man-made challenges and it's a such a drag."

That's not to say Aniston has never been on Instagram. While married to Justin Theroux, she periodically popped up in his feed, and earlier this month, she posed in a selfie with Cox and LeBlanc that was posted on Cox's Instagram next to Cox's caption, "A rare night and I love it."

Aniston has been getting a lot of love since posting her first pic on Tuesday morning. Her comments section has been flooded with words from famous friends like Mindy Kaling, who wrote, "OMG welcome to the internets," while ex-husband Theroux posted, "Woot-Woot" alongside a heart and #first. Cox simply wrote, "love you," while Erin Foster typed, "This is big."

And it is. Aniston's official Instagram outing comes as the actress is prepping for the launch of her new Apple TV show, The Morning Show, in which she stars opposite Steve Carell and Reese Witherspoon, the latter of whom has proven herself to be a bit of a social media expert. Witherspoon has more than 19.5 million Instagram followers and 2.6 million on Twitter, and she had a recent viral post about TikTok.

One would expect a lot more behind-the-scenes content from Aniston and Witherspoon from the set of The Morning Show, a series they both produced together. The show is set to premiere Nov. 1. Until then, social media gurus will be keeping a close eye on Aniston's account, which is snagging followers by the second. As of 10:45 a.m., Aniston already had amassed 524,000 followers and become a trending topic on Twitter.

By Wednesday morning, Aniston's followers had spiked to more than 8 million. She also has been flooding her Instagram Story with welcome posts from her famous Insta friends, including her Friends costars.

Aniston broke the Guinness World Records title for the fastest time to reach one million followers, in 5 hours and 16 minutes. This is the third time the record has been broken in 2019, first by K-Pop star Kang Daniel and then by Prince Harry and Meghan Markle.
