On Tuesday, several Avengers 4 set photos seemed to suggest that Gwyneth Paltrow would return to play Pepper Potts in the film. Now, a handful of new images indicate there was a key piece of her wardrobe that wasn't visible in those earlier images: an engagement ring.These new set photos show Pepper and longtime love interest Tony Stark embracing, with what appears to be an engagement ring clearly visible on her left ring figure. As they're wearing the same clothes from Tuesday's photos and filming on Avengers: Infinity War has already wrapped, it seems that the scene will take place in Avengers 4. It's unknown how the engagement might factor into Infinity War.RELATED: Avengers: Infinity War: Tom Vaughan-Lawlor Cast in Villain Role

Paltrow’s Pepper Potts was conspicuously absent from Avengers: Age of Ultron, despite the fact that she was romantically involved with Tony Stark. Her absence was explained away in Captain America: Civil War, where Tony revealed that they were taking a break. Because of this, many speculated that Paltrow would not reup her contract with Marvel Studios. However, Paltrow made her Marvel Cinematic Universe return in Spider-Man: Homecoming, where she and Tony intended to throw a news conference about the Avengers’ latest recruit before Peter Parker voluntarily backed down. There, Pepper’s relationship with Tony seemed to take a turn for the serious when Tony revealed his intentions to propose. Though the film concludes without showing Pepper’s answer to Tony’s big question, these set photos appear to confirm that Pepper does indeed say yes.
