Ryan Reynolds Jokes About On-Set Drama With His and Blake Lively's Daughter Inez

The 7 year old made a cameo in 'Deadpool & Wolverine.'

Deadpool & Wolverine was a family affair for the Lively-Reynolds household, between Blake Lively's viral appearance as Lady Deadpool and each of their kids making cameos in some way (Betty was credited as the Hugh Jackman wrangler). Working with relatives, however, isn't always for the faint of heart. One member of the Lively-Reynolds clan proved to be a bit difficult on set—and it wasn't Reynolds or Lively.

On Thursday, Reynolds, who plays Deadpool, shared a production still from the movie that captures him in costume alongside his and Lively's 7-year-old daughter, Inez, in her Kidpool ensemble. Reynolds acknowledged the little one's film appearance the only way he knows how: by trolling her. In his caption, he teased that the actor playing Kidpool is quite skilled in "backtalk."

"Only costar I argued with," he wrote alongside the snap. "Most people think Kidpool is the dirtiest. But she’s also pretty good at backtalk and never taking out the trash."

Lively also reflected on her role as Lady Deadpool in the film, which hit theaters on July 26. She posted a roundup of photos from the premiere, in addition to a snap of her in her red premiere jumpsuit, a sketch of her character carrying Deadpool, and an action figurine of Lady Deadpool.

In her caption, she recounted the first time Reynolds shared his idea to create the "meta" superhero and how her involvement came to be.

"In 2010 I was on Gossip Girl and about to film my first superhero movie, The Green Lantern with my kind Canadian costar @vancityreynolds He told me, our other costar, another superhero newby @taikawaititi and all of us about @deadpoolmovie for the first time. It was a 'meta' superhero," she explained. "Most of us didn’t know what exactly meta meant back then. Except Taika bc he’s always been more brilliant than the rest of us mortals. We understood in theory, but how it would come together for an audience was murky, for everyone but him. It wasn’t a real dream. The movie was never gonna happen."

"Just before all this in 2010, @robliefeld drew an unmasked Lady Deadpool for the first time, go to the next slide for his words. @deadpoolmovie wasn’t real. And Rob had no idea I was working with @vancityreynolds," she continued, referencing the creator of Deadpool Rob Liefeld's post about how Lively served as the inspiration for Lady Deadpool years ago. How so? Because he and his wife were fans of Gossip Girl. "12 years later I read Rob’s post. A year after that, @deadpoolmovie 3 was filmed. And today it’s in theaters. The universe has such a magical sense of humor sometimes."
