Shooting is currently underway on 2019’s Avengers 4, after cast and crew wrapped on ‘s Avengers Infinity War earlier this summer.

Yesterday saw Iron Man trio Downey Jr’s Tony Stark, Gwyneth Paltrow’s Pepper Potts and Jon Favreau’s Happy Hogan

While filming an intimate scene between Downey Jr and Paltrow, a ring was spotted on the actress’s left hand.

It looks like Tony and Pepper are engaged to be married, but will they both survive Avengers 4?

The 44-year-old actress even leaked the news on her Instagram with a photo of her and Downey Jr.

Paltrow wrote: “We’re back! #pepperony #[engagment ring emoji] #infinitywars.”

Having been on a break during Captain America: Civil War, Tony and Pepper were reunited at the conclusion of Spider-Man: Homecoming.

After Peter Parker declined joining the Avengers as Spidey, Pepper was wondering what to do with the press conference.

After a joke about a proposal, Happy quickly threw Tony the engagement ring before following Pepper into the room full of reporters.

Perhaps that was the moment Tony proposed to Pepper and why Paltrow was happy to leak the news on her social media.

Avengers: Infinity War is released in UK cinemas on April 27, 2018, while Avengers 4 will follow on April 26, 2019.
