"Move fast and break things" may be Facebook CEO Mark Zuckerberg's much-quoted motto, but he may want to pass it onto one of his platform's newest record-setting users: Jennifer Aniston.

The 50-year-old "Friends" star joined Instagram on Tuesday morning. If that wasn't enough to cause a stir, the first photo she posted from her account was a selfie featuring her fellow co-stars from the beloved show: Lisa Kudrow (Phoebe Buffay), Courteney Cox (Monica Geller), Matt LeBlanc (Joey Tribbiani), David Schwimmer (Ross Geller), and Matthew Perry (Chandler Bing). 

Almost immediately, news of Aniston's Instagram debut led to an influx of followers, likes, and comments - which spurred technical problems, and made it difficult for some users to follow Aniston's account.

But while the issues have since been resolved, there are some things that remain broken. Guinness World Records announced Wednesday that Aniston had broken the record for the fastest time for an Instagram account to reach one million followers, reaching the milestone in just five hours and 16 minutes.

Aniston's record-setting Instagram account beats a record previously held by the account @sussexroyal, the official Instagram for the Duke and Duchess of Sussex, Prince Harry and Meghan Markle. They reached one million followers earlier this year in April in a time of five hours and 45 minutes.

Before that, the record belonged to K-pop star Kang Daniel, who reached one million followers in 11 hours and 36 minutes.
