Rupert Grint beats David Attenborough's Instagram world record

Harry Potter star Rupert Grint has broken David Attenborough's Instagram record by becoming the fastest user to hit a million followers.

He joined Instagram earlier this week to share a picture of his baby girl - Wednesday G. Grint.

Within four hours and one minute of posting, Grint crossed the one-million followers' mark. 

Meanwhile, Attenborough, who had joined the social media platform earlier this year, took four hours and 44 minutes to get to the same total.

Taking to Instagram, the actor joked about being 10 years late in joining the platform!
