ET was on the set of XXX: The Return of Xander Cage, where Vin Diesel explained that when he comes home after a long day of being an action star at work, he's just an ordinary dad.
The third explosive chapter of the blockbuster XXX franchise follows Xander Cage (Diesel) after he comes out of self-imposed exile to set out on a collision course with deadly alpha warrior Xiang and his team in a race to recover a sinister and seemingly unstoppable weapon known as Pandora's Box.
The flick raises the bar on extreme action with mind-blowing stunts, which Diesel does all on his own, including one where he rides a motorbike underwater!
After watching their fearless leader tackle the badass tasks called for in the script, the cast got to see a softer side to the actor when his kids came to set.
"He's just a bundle of warm, fuzzy joy," said Nina Dobrev.
"He's just a big teddy bear," Ruby Rose added. "I was like, 'I want my kids to be exactly like these guys!'"
Diesel has three children with longtime girlfriend Paloma Jimenez -- 8-year-old daughter Hania, 6-year-old son Vincent and 1-year-old daughter Pauline. He explained that when it comes to his movie stunts "they just want [him] to be safe."
"At home, I'm just Daddy," he said.
XXX: The Return of Xander Cage, also starring Samuel L. Jackson, Conor McGregor, Toni Collette and newcomer Miss Universe runner-up Ariadna Gutierrez, hits theaters on Jan. 20, 2017.
