Blake Lively is seen kissing her husband Ryan Reynolds while he is dressed up as Deadpool as fans speculate she plays Lady Deadpool

Blake Lively shared a very rare photo to Instagram on Monday morning.

The blonde beauty was seen kissing her husband Ryan Reynolds while he was dressed up on the set of his new Deadpool movie.

It was a professional photo shot by their longtime friend Guy Aroch to promote the new film with Hugh Jackman, 

Lively, 36, said in her caption she was 'proud' of her spouse for the work he put into the project.

It also appears that she has a red costume of her own on suggesting she plays Lady Deadpool, which has been widely speculated.

Deadpool & Wolverine opens on July 26. 

'Brb I’m buying milky pens to write your name on my hand @vancityreynolds,' began Blake's Instagram caption.

She then went on a fun rant. 

'My y2k girlies, I should be competitive bc @itendswithusmovie is coming out in 3 weeks BUT when your middle school obsessions, your feelings post baby, or about Nice men who use feminism as a tool, your love of the Wizard of Oz, Succession, Sandy & Danny, driving with Avril blasting, the way the choreography of a certain boy*band song got me, of Baz Luhrmann fireworks to punctuate a moment, even down to the fact that our hair color is determined by seasons and the French method by which it’s painted are all so seen… 

'MY WORD… it’s hard not to encourage my ladies to spot all the ways we’ve influenced @deadpoolmovie I’ve never been more proud. And I’ve given birth 4 times. ❤️.'

Ryan and Blake have four children together: daughters James, Inez, Betty, and a fourth child whose name they have yet to share.

This comes after Ryan made a joke about a friend.

Reynolds said Taylor Swift’s babysitting fee for his and his Blake’s four children is 'cost-prohibitive.'

Hugh Jackman started the conversation with E! News as he said Swift was Ryan's nanny.

'The cost of that is … I believe the accountant said, "Cost-prohibitive,"' Reynolds replied. 'But I think what he meant was, "Cost-insane-what-are-you-doing-I’m-no-longer-you’re-accountant."'

Last week Blake announced the latest addition to the Betty Buzz line, two mocktail flavors: Sparkling Apple Ginger Sour Cherry and Oak Smoked Lemonade.

Blake promoted the drinks with a makeup-free selfie on Instagram.

In the first picture, the Gossip Girl alum posed in front of the newest drink wearing a white tank top. 

Blake looked fresh-faced, and her long blonde hair fell freely. 

A second shot showed a cheeky commercial for the mocktails.

'Research says product videos boost sales up to 9.7%,' Blake is heard saying as sparkling water is being poured over a series of fruits. 'Is it working yet? Light, refreshing. Crafted for foodies.'

The It Ends with Us star teased, 'This feels like it's working.'

'INTRODUCING MOCKTAILS,' Blake captioned the post. 'Safe for all ages. They're like soda if it was made of fresh fruits & garnishes. Or sparkling water if it was an everlasting gobstopper of flavor. Enjoy! :) 40% of on @amazon until the end of day TODAY.' 

Betty Buzz first launched in 2021 with sparkling mixers before Blake launched a line of canned cocktails under the sister brand Betty Booze. 

The two mocktail flavors are non-alcoholic versions of the Betty Booze options.

Meanwhile, Reynolds took to his Instagram Stories to support his wife in his usual humorous fashion.

The Deadpool actor reposted Blake's selfie with a link to purchase the drinks.

Ryan wrote '40% off', with a tiny font disclaimer clarifying the sale in the bottom right corner: 'The drinks... not my wife.' 

Blake also took to her Instagram Stories to share a selfie with the cherry and lemonade mocktail cans alongside a picture of the Deadpool & Wolverine art - her husband's newest movie. 

'My camera roll has a real palette going these days,' the Age of Adaline star said. 'You like what you like.' 

The couple has continued to support - and troll - one another since first tying the knot in 2012. 

And these days, along with her Betty Buzz line, Blake is on a press tour ahead of the release of her latest movie - an adaptation of the Colleen Hoover novel, It Ends with Us.

'If audiences had half the amount of fun we did, we're gonna put theme parks outta business. In 20 years of doing this, I don't think I've ever experienced anything quite like surprising 2500 fans with an early preview of @itendswithusmovie,' she gushed on Instagram.

'To everyone who showed up in their floral jeans alongside us, including @brandonskleanr (jeans handmade by me & @isabela.ferrer). @colleenhoover being MOTHER in every way, turning it OUT for everyone at @book.bonanza.'

Blake added, 'I loved eating delicious food with @alexsaks &co. Drinking alarming amounts of coffee. Bringing the hottest plus one, my mother in law @tamtam1944. The highlight though was when I got to style sweet @isabela.ferrer in my clothes because she came straight from her job at a restaurant in Brooklyn to this mayhem bc @colleenhoover and I begged her to just hop on a plane.

'The best weekend, and this is only the beginning...' she concluded.

In June, the A Simple Favor actress reflected on starring in the film. 

'Some people will always like a book better than a movie and some people like a movie better than the book,' she told Entertainment Tonight, 'but I think that we just did our best to honor the book and honor the fans, and, I think, really make something that works even by itself.'

'If you don't know the book, the movie works. I don't think there's any way that if you read the book and you saw the movie that you wouldn't be thrilled. We really worked hard on that,' she continued. 'I also believe if you saw the movie and then read the book, you wouldn't go, 'Hold on, this isn't like [the other].' You can do either. I think they're both really beautiful.'

And Colleen agreed with her leading lady's sentiments, telling the outlet, 'Readers tend to always want to read the book first. I completely understand that, but I feel like this adaptation has stayed so true to the book that it's actually either or, whatever you prefer. I think that you'll be happy if you watch the movie and then go into the book or vice versa.'

The novel is based on Colleen's parents' relationship and follows Lily Bloom (Blake) as she navigates a volatile relationship with Ryle Kincaid (Justin) amid the reappearance of her first love, Atlas Corrigan (Brandon Sklenar). 

'This is the book that means the most with me,' the author shared. 'I've tried to have other books adapted and it didn't quite go to fruition. I've been praying this would happen for four or five years now, so it just means so much to me. This book is the one that's personal to me, so to get to see it on screen [is meaningful]. I watched it for the first time with my mother, who inspired the story, so words can't express how amazing this whole experience is.' 

Blake noted about This Ends with Us: 'This story resonated with so many people, so there's a great responsibility that comes with that.'

'You want to honor this book and this character that people love so much, but you also want to bring a life and a humanity to it that is true to who you are,' she said. 'It's a lot of different things that you want to accomplish in this story.'

Meanwhile, this film is something Blake is 'so proud of.'

'I'm just so proud to be here and sharing it with Colleen and the fans,' the Shallows actress added. 'It's just really special. It was a great honor to take on Lily, and I'm so proud.'
