It was Chris Evans' 40th birthday this weekend so naturally, his celebrity friends (including Chris Hemsworth) were going to troll him.
Among the more sincere birthday wishes to Chris Evans was this one from Mark Ruffalo.
In a post on Instagram, he wrote: "Sending all the virtual hugs to you on your birthday, brother! Two can play the 'no phones on set' game, @chrisevans."
However Chris Hemsworth wanted to take the opportunity to take the piss.
"Happy 40th birthday Chris Evans, you'll always be number 1 in my book," the 'Thor' star captioned a photo of himself alongside Chris Pratt.
Fans absolutely loved it.
Many wanted to get in on the joke, with one writing: "That's not Chris Evans, it's Chris Pine."
The battle of which is the best Chris between Chris Evans, Chris Hemsworth, Chris Pratt and Chris Pine has been ongoing for a while now.
Previously Chris Pine (the only Chris to not star in the MCU, though he plays Steve Rogers in the DCEU) has had to explain which Chris he is; plus the internet lost it last year when Chris Pratt was voted the worst Hollywood Chris.
The Chrises have frequently been mistaken for one another too.
Maybe the battle will end when one of them wins an Oscar? Who knows, really.
