The Portuguese footballer is the first person to cross the 400 million followers mark, just behind the official account of Instagram with over 469 million followers.
Ronaldo celebrated his 37th birthday on Saturday and posted a photograph that received almost 14m likes.
The five-time Ballon d’Or winner thanked his fans for their best wishes and wrote: “Life is a roller coaster. Hard work, high speed, urgent goals, demanding expectations.
“But in the end, it all comes down to family, love, honesty, friendship, values that make it all worth it. Thanks for all the messages! 37 and counting!”
