 And now we’re Instagram FRIENDS too. HI INSTAGRAM A post shared by  Jennifer Aniston (@jenniferaniston) on Oct 15, 2019 at 6:03am PDT

The photo features Courtney Cox (Monica Geller), David Schwimmer (Ross Geller), Matt LeBlanc (Joey Tribbiani), Lisa Kudrow (Phoebe Buffay) and Matthew Perry (Chandler Bing). The photo was apparently taken when they had dinner at Cox's house.

They celebrated the 25th anniversary of the series' pilot episode. Almost immediately after her debut on the social media platform, it led to an influx of followers, comments and likes -- which even resulted to technical problems.

In just five hours, the 50-year-old actress received 1 million followers, setting an official mark recognized by the Guinness World Records for the fastest time for an Instagram account to reach that milestone.

She has beaten the record previously held by the account @sussexroyal, the official royal Instagram for the Duke and Duchess of Sussex, Prince Harry and Meghan Markle. In April, they reached 1 million followers in 5 hours and 45 minutes.

Before them, the record belonged to Kang Daniel, a Korean pop star who reached 1 million followers in 11 hours and 36 minutes.

Cox also shared a picture on Instagram with Aniston and LeBlanc, captioning it, "A rare night and I love it."

A 'Friends' Reboot

TV shows like "Sex and the City" and "Baywatch" leaped to the big screen, but fans of the '90s sitcom "Friends" had been hoping that there will be a movie.

In an interview with Howard Stern, Aniston crushed the hopes of a reboot. She revealed that there might be some interest in a movie, but producers wouldn't allow it.

When asked if her former co-stars would be open to reprising their roles, she added:

"It depends. We haven't all sat in a room. But would we have loved to have done something together? Yeah. It would have been fun. We could have redesigned it for a couple of episodes. But whatever. Maybe it's better this way; we'll never know."

Stern then asked how if she missed being back on the set. She told him "We miss it every day. I would be nothing without it."

Aniston was surprised that until this day, people are still watching "Friends" reruns on Netflix, 25 years after it first premiered.

"It's a phenomenon that I am amazed by. To have a whole new generation of children adoring the show as much as they did back in the day when it was airing for the first time is incredible."

Creator Marta Kauffman, with co-creator David Crane, said that a reboot could ruin the show's legacy.

Speaking to the Rolling Stone in 2013, Kauffman said that the show is about a time in your life when your friends are your family. However, now is not that time anymore.

She believes that all they would do is put together six actors, but the heart of the show would be gone. Hence, the reunion could only disappoint.
