Later she was dethroned by naturalist Sir David Attenborough and today, Entertainment Tonight reports that Harry Potter alum Rupert Grint took the crown. He hit the one-million-follower milestone in just four hours and one minute. Back on Wednesday, on Nov. 10, Grint joined Instagram and shared a photo of himself with his newborn daughter, Wednesday G. Grint. "Hey Instagram....only 10 years late, but here I am. Grint on the Gram!" he wrote in his debut. "Here to introduce you all to Wednesday G. Grint. Stay safe, Rupert."

"I don't believe it. It's very, very surreal," Grint said. "I never thought I would [join Instagram]. I always said that I wouldn't, and then I just thought, 'It's been such a crazy [time]. So why not?' It's insane." He was humble though, letting his daughter take the credit for his social media fame. "I think Wednesday actually broke the internet, personally. She gets the credit," he finished.
