Sir David Attenborough has joined Instagram and broken Jennifer Aniston's record for the fastest time to accrue a million followers.

According to Guinness World Records, the broadcaster and natural historian reached the milestone in a little over four hours, comfortably beating Aniston's previous record of five hours and 16 minutes.

At the time of writing, Attenborough has 2.9 million followers and counting. Underneath his first post, he received welcome messages from tennis star Sir Andy Murray, rapper Young Filly and the World Wildlife Fund, among many others.

In his first post, Attenborough said he has decided to join Instagram to help spread the message that "the world is in trouble."

"Continents are on fire. Glaciers are melting. Coral reefs are dying. Fish are disappearing from our oceans. The list goes on and on," he said. "But we know what to do about it – and that's why I'm tackling this new way, for me, of communication. Over the next few weeks I'll be recording messages to explain what the problems are, and how we can deal with them."

Though Attenborough will be recording video messages for Instagram, the account will be managed and run by his frequent collaborators, Jonnie Hughes and Colin Butfield, who've also worked with him on his upcoming book and Netflix documentary A Life on Our Planet.

Back in June, we learned that Attenborough, 94, was being productive as ever putting the finishing touches to his latest BBC documentary series A Perfect Planet at his home in southwest London. He was also moonlighting as an online science teacher during the U.K.'s coronavirus lockdown earlier this year.

Attenborough said of A Perfect Planet when it was announced in February: "Oceans, sunlight, weather and volcanoes, together these powerful yet fragile forces allow life to flourish in astonishing diversity. They make Earth truly unique, a perfect planet. Our planet is one in a billion, a world teeming with life. But now, a new dominant force is changing the face of Earth: humans. To preserve our perfect planet we must ensure we become a force for good."
