They share the same first name and are both superheroes in the blockbuster Marvel action movies.

And on Tuesday, Chris Hemsworth, 39, paid a cheeky tribute on Instagram to his Avengers co-star Chris Evans to mark his 42nd birthday.

Chris posted of photo of him and Evans both rocking a matching smart casual look at an event and captioned it with some hilarious words.

‘Happy birthday to my favourite Chris,’ he wrote alongside the snap of the Knives Out star.

Hemsworth has a history of trolling both Chris Evans and another Marvel co-star namesake, Chris Pratt from the Guardians of the Galaxy movies.

Finding out who is the ‘best Chris’ has been a long-running gag amongst the three actors, who have portrayed Thor the God of Thunder, Captain America and Peter Quill a.k.a. Star Lord in over a dozen films.

It comes after Chris Hemsworth and his wife Elsa Pataky, 46, visited the Spanish actress’ hometown of Madrid this week.

Elsa shared a series of photos via her Instagram account on Sunday surrounded by her Spanish family, including a loved up photo of her hunky Aussie beau.

‘Enjoying my home town Madrid with my love ones,’ Elsa captioned her post.

The couple touched down in Madrid last week to attend the red carpet premiere of Chris’ new film Extraction 2.

The actor was hilariously busted with Spanish words scribbled on the palm of his left hand when he stepped out at the event.

As Chris waved and happily signed autographs for the crowd, he was seen with Spanish words scrawled in blue pen on the inside of his hand.

The Hollywood actor has been married to his Spanish wife for 13 years – but it appears he’s yet to learn the language.

The Thor star took the blunder in good humour, addressing it in an Instagram post on Thursday.

‘After years of coming to Spain and being asked ‘has my Spanish improved’ I can safely say it’s in the palm of my hand,’ he joked.
