Her role in the third installment of the action film franchise -- set to be released Jan. 20, 2017-- will mark her feature film debut. In addition to Diesel, Gutiérrez also joins already-announced stars Deepika Padukone, Ruby Rose, Nina Dobrev, Toni Collette, Donnie Yen, Conor McGregor and Samuel L. Jackson.

Diesel, who starred in the original xXx in 2002, is already gearing up to reprise his role as Xander Cage, taking to Instagram on Tuesday to share a shirtless photo of himself in character on a skateboard.

"Xander state of mind…," he captioned it.

The 48-year-old actor has been sharing behind-the-scenes photos from the film's Dominican Republican set to his Facebook page. Earlier this month, he penned a lengthy message about replaying the iconic character, while gushing about his costars.

"Fifteen years… it has been fifteen years since I have embodied the character of Xander Cage," Diesel, who was absent from 2005's xXx: State of the Union sequel starring Ice Cube, explained. "The smile you see on my face is real and reflective of the joy that comes from returning to a role that was so important and rewarding to me."

"As a producer, the idea we were able to put together such an amazing cast is surreal," he continued. "You hear me say often that this might be one of the best casts ever assembled and I don't expect you to understand that until you see the movie next year... haha, but it is true on such a global level."

"What is all the more impressive is how much each person is bringing to the table," he added. "Ruby Rose represents that perfectly. She's been training like crazy, not just to be physically primed but to truly embrace her respective character, and Adele's specific skill set. When actors come with that level of commitment you know you have a blockbuster on your hands."

@vindiesel - Late Last night I was caught taking a nap on set late during a lens change...And by on set I mean on Vin. Growing up I watched this man through XXX and fast... First I imagined what it would be like to be him, As I got older I wondered how it would be to work with him. He was the hero and anti hero in one. He protected people but unlike other secret agents on the screen - I related to Vin. His energy was always so palpable. He always made me laugh, he did the best stunts and he ALWAYS got the girl. Yet he didn't take himself seriously..I wanted to live like that. I never dreamed I'd step into a role from a movie I grew up watching, with a guy I idolized who I probably had a poster of on my wall. My life is always surprising me and I am always grateful but more than the work I get to do and dream I get to live, I'm grateful for the people I have met who love me as I am and are true friends. Like my man Vin.. Who is a reminder to always stay true to yourself and always trust your destiny. When I was young I escaped through movies.. Now I hope to be in movies that you can escape into and find laughter, confidence to be you, hope or even just a break from the situations you may be facing. Xox

The xXx sequel isn't the only action film Rose has had to heavily train for -- last December, ET reported that the Orange Is the New Black actress was hard at work in the gym for her role in John Wick 2, the sequel to the 2014 Keanu Reeves thriller.
