The 94-year-old naturalist debuted on Instagram today (24 September) and it only took him four hours and 44 minutes to reach a million followers.
Dave quite rightly, some might say, took the record from Friends' Jennifer Aniston. She got the coveted one million in five hours 16 minutes when she joined Insta in October 2019.
His first post was an IGTV video warning about climate change, with the first story post showing an introduction to the two blokes behind the account.
Account runners Collin Butfield and Johnnie Hughes worked with Sir David on A Life On Our Planet, an upcoming Netflix documentary.
They explained: "Social media isn't David's usual habitat so while he's recorded messages solely for Instagram, like the one in this post, we're helping to run this account."

In the video, Sir David says: "I've been appearing on radio and television for the past 60 years, but this is my first time on Instagram.
"As we all know, 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.
"But we know what to do about it so 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.
"Join me, or as we used to say in those early days of radio - stay tuned."
Earlier this month, Attenborough issued a warning about our planet 'facing a crisis' after experts said one million species are now under the threat of extinction.
He urged people to take action now for a 'better future' with an hour-long documentary, Extinction: The Facts, which explores the devastating effects human action has had on the natural world.
The film shows us horrific scenes of destruction, including a sequence in which monkeys leap from trees and into a river to escape a fire. In another, a koala limps across a road, searching for shelter as its forest home is engulfed in flames.
Discussing the show, he said: "Over the course of my life I've encountered some of the world's most remarkable species of animals.
"Only now do I realise just how lucky I've been - many of these wonders seem set to disappear forever."
