Ryan Reynolds and Blake Lively’s daughter Betty made her mark on Deadpool & Wolverine!

Her dad Reynolds, 47, might have been one of the stars of the movie and her mom Lively, 36, had a cameo, but the couple’s third child, 4-year-old Betty, wasn’t going to miss out on the fun.

In a video shared on TikTok on Saturday, July 26, the credits are shown rolling at the end of the movie, revealing a very sweet role the little girl had on set: “Hugh Jackman Wrangler: Betty Reynolds.”

While the credits didn’t elaborate on what Betty’s specific duties were, Reynolds has previously spoken about the cute relationship his daughter has with Jackman, 55.

On Monday, July 22, Reynolds and Jackman attended the movie’s premiere at the David H. Koch Theater in New York City and discussed what it’s like to bring their kids on set of a MCU movie.

“I don’t profess that my kids are perfectly behaved,” Reynolds joked to PEOPLE.

“My four-year-old Betty sort of loves Hugh, like unconditionally,” he explained as Jackman, standing beside him, chuckled.

“And she expresses that love through unblinking violence,” he added. “So she attacks him, thinking she has claws and he has a healing factor — which he might.”

Meanwhile, Betty isn’t the only Reynolds-Lively child who had a role in the movie, as her three siblings all appeared onscreen in the new film.

Inez, 7, makes a surprise cameo as a character named Kidpool, while James, 9, is credited on IMDB as playing a Screaming Mutant. Olin, 1, is also given a credit for playing Babypool.

Reynolds opened up about Olin, and revealed that he is a boy, in an emotional video shared on Instagram on Friday, July 26, in which he shared his bond with a Wrexham AFC fan, John Bell, who turned his grief over the death of his late son Jake into something positive through his charity organization, Walking 4 Hope.

“I want to share with you that I too have a son and that if … boy, John, if I love him one-tenth as much as you love Jake, I feel like I’ve done a pretty damn good job,” Reynolds said.

Deadpool & Wolverine is now playing in theaters.
