Marvel fans already got a glimpse into the storyline for one of 2019’s most hotly-anticipated movies after Gwyneth Paltrow confirmed her alter-ego Pepper Potts was engaged to Tony Stark earlier this week.

And the actress, 44, and her screen beau Iron Man – portrayed by Robert Downey Jr, 52 – seemed to be celebrating their happy news as they shot scenes for Avengers 4 on set in Fayetteville, Georgia, on Tuesday.

Sharing a passionate kiss, the pair puckered up for a PDA as Gwyneth’s character showcased her sparkling diamond engagement ring in all its glory.

Downey, in character as Tony Stark, held on to his on-screen love for the sweet shot, captured by multiple cameras on set.

The actress was decked out in tight athletic wear, accentuating her curves in a pair of navy Alo Yoga leggings, and had her hair pulled back into a tight ponytail.

Earlier this week, Gwyneth shared a photo to Instagram with her co-star with the caption: ‘We’re back.’

But it was the engagement ring emoji she included that held the big news for the Marvel Cinematic Universe.

The PDA-packed filming comes after Downey joked that his glamorous co-star was his ‘free pass’ from wife, producer Susan Levin, 43.

The couple have been married since 2005 and raise two children together; Exton Elias Downey, five, and Avri Roel Downey, two.

In May, Downey told Howard Stern that he was keen to get Gwyneth back into the Iron man films so they can hook up.

‘My free pass – because her and Susan are such good friends – is Paltrow,’ he revealed.

But there is a catch: the cameras have to be ‘rolling on a take’ for them to legally lock lips.

Confirmation: Earlier this week, Gwyneth shared a photo to Instagram with her co-star with an engagement ring emoji

‘I gotta get her back in these movies so I can make out with her onscreen again,’ he concluded.

Fans who watched Spider-Man: Homecoming knew the superhero had popped the question to his assistant-turned-lover at a press conference right at the end of the film, but never actually got to hear her answer.

Speculation the characters were affianced grew when the Goop creator was spotted sporting a massive sparkler on her finger on the Georgia set of the upcoming crossover sequel.

Some had theorized Gwyneth had secretly got engaged to real life boyfriend, producer Brad Falchuk.

Dream team: Downey Jr shared a pic of the ‘Infinity trinity’, which included himself, Gwyneth and executive producer Jon Favreau, who also plays his right hand man Happy Hogan

Filming for the superhero movie has already wrapped, so Gwyneth’s scenes either were late add-ons, or were part of the Infinity War sequel that is being shot back-to -back with part one.

The day before, Downey Jr shared a pic of the ‘Infinity trinity’, which included himself, Gwyneth and executive producer Jon Favreau, who also plays his right hand man Happy Hogan.

Filming for part two, due in theaters in May 2019, is set to continue until December.

Avengers 4 boasts a long list of Marvel actors, including Scarlett Johansson, Chris Evans, Chris Hemsworth, Tom Hiddleston, Josh Brolin, Chris Pratt, Elizabeth Olsen, Paul Bettany, Tom Holland, Zoe Saldana, Benedict Cumberbatch, Evangeline Lilly, Karen Gillan, Anthony Mackie and Jeremy Renner.
