Is Pepper Potts engaged to Iron Man? New Instagram pic sparks buzz

After confirming fans that Gwyneth Paltrow will be appearing in 'Avengers

Recently, the 44-year-old actress shared a selfie with her co-star, Robert Downey Jr, or soon-to-be 'on-screen husband' from the set of her new multi-starrer superheroes flick.

She captioned the photo, "We're back! #pepperony #infinitywars"

The engagement ring emoji, captioned on the picture, created quite the buzz. Many fans started speculating that 'Pepper' might have finally married her long-time love, Stark Industries CEO, Tony Stark.

At the end of 'Spider-Man: Homecoming, the superhero had a ring in his hand and was planning to propose to his assistant-turned-lover at a press conference right at the end of the film.

'Avengers: Infinity War' boasts a long list of Marvel actors, which includes Chris Evans, Chris Hemsworth, Scarlett Johansson, Mark Ruffalo, Chris Pratt, Tom Hiddleston, Benedict Cumberbatch, Tom Holland, Zoe Saldana, Elizabeth Olsen, Evangeline Lilly, Karen Gillan, Anthony Mackie, Jeremy Renner, Paul Bettany, and Josh Brolin.

'Infinity War' is scheduled to be released in 2018.
