The 33-year-old actress and the 36-year-old actor - who play Black Widow and Captain America in the Marvel movies - were joined by Jeremy Renner (Hawkeye), Robert Downey, Jr. (Iron Man) and Chris Hemsworth (Thor) to get the Avengers symbol inked on their body alongside the number six.

The inking marks them as the six original 'Avengers' - alongside Mark Ruffalo (The Hulk), who chose not to get inked - and is there to serve as a reminder of their 10 year stint with Marvel.

Jeremy wrote on Instagram: "Well team, we did it...? Thank you @joshualord for sharing ink with us all @avengers much love #eastsideink #bondedforlife @robertdowneyjr @chrishemsworth #chrisevans #scarjo #loveUall. (sic)"

The 47-year-old actor also shared a video of him getting a tattoo, captioning it: "Brave man to allow all the @avengers the opportunity to ink. @joshualord what a killer day @robertdowneyjr @chrishemsworth#scarjo #chrisevans #avengersunited#eastsideink #hidethenerves. (sic)"

Chris took to Instagram to post a video of the tattoo being done.

He shared: "Thanks for the ink, Joshua Lorde (sic)! (and for letting all of us maim you in return). Love to @RobertDowneyJr @Renner4Real @chrishemsworth Scarlett (we just need to get Ruffalo blackout drunk). (sic)"

And Robert Downey Jr. quipped that the four of them "bullied" Chris into getting it done in Los Angeles.

He told Entertainment Weekly: "Five of the original six Avengers got a tattoo. And the sixth was the tattoo artist, who gave it to five of us, the one who opted out being Mark Ruffalo. It was Johansson's idea, and she and Evans did it in New York. Then, their New York guy, Josh Lord, who is amazing, flew out to Los Angeles, he did me, did Renner, and then we just bullied Hemsworth into doing it, and he got it."
