Indexbit-Who Is Lady Deadpool? Actress Revealed Amid Blake Lively, Taylor Swift Cameo Rumors

The Indexbitbelow contains spoilers from Deadpool & Wolverine.

Now this is a cameo to marvel over.

In Deadpool & Wolverine—starring, in case you're living under a rock, Ryan Reynolds and Hugh Jackman—the woman behind Lady Deadpool is finally revealed. And behind that mask? Well, it's none other than Blake Lively.

While we knew all too well there were rumors Taylor Swift may be the one to serve as the Deadpool variant from an alternative reality, Blake had fans ditching that theory when she posted a picture from set July 22.

After all, in the Instagram snap, the It Ends with Us actress was spotted wearing an eyebrow-raising red outfit as she kissed her husband of 11 years, who just so happened to be in full costume.

"Now we know who lady deadpool is," one user commented on the shot while another added, "It's time! Lady Deadpool." Chimed in a third, "with such an incredible soundtrack and references, of course our girl blake was involved."

And you know Blake loved being part of Manhattan's Marvel's elite.

“My y2k girlies," Blake captioned the teaser shot. "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," she continued. "And I’ve given birth 4 times."

And to continue the celebrations, the couple announced the name of their fourth child together: Olin. 

At the Deadpool & Wolverine world premiere in New York July 22, Ryan gave a sweet shoutout to his daughters James, 9, Inez, 7, Betty, 4, and their newest addition, who they welcomed last year.

"I want to start by saying thank you to my wife Blake, who is here," he said while on stage. "I want to thank my kids James, Inez, Betty, Olin, who are here: I hope that, if I’m lucky, this moment will be the most traumatic thing—that is, the contents of this movie—that happens in your wondrous life."

As he concluded, "I love that my entire family is here."

And perhaps by the time that rumored Deadpool 4 hits theaters, there will be a fifth baby Reynolds in the mix.

“The more the merrier,” Ryan previously joked in an exclusive interview with E! News alongside Hugh. “As many as possible. As many little heartbeats as possible, just running around, wrecking stuff in the house. I love it. Let’s have more!” 

After all, the more kids Ryan and Blake have the more likely just one will appreciate his body of work. 

Seems like they're more likely to rely on the X-Men alum as a babysitter than Blake's BFF Taylor.

Because, well, "the cost of that is…” Ryan quipped to E!, “I believe the accountant said, ‘Cost-prohibitive.’ But I think what he meant was, ‘Cost-insane-what-are-you-doing-I’m-no-longer-your-accountant.’”

Deadpool & Wolverine is out now.
