Break out the tissues.
Paul Walker and Vin Diesel's deep friendship obviously went beyond just being co-stars -- and now Diesel has found a touching way to keep the late Walker's memory alive.
In an interview on Today on Monday, the 47-year-old Furious 7 star revealed that he named his newborn daughter Pauline after his beloved co-star and "brother."
"He [Walker] was in the room. There's no other person that I'm thinking about as I'm cutting this umbilical cord," he told Today's Natalie Morales. "I knew he was there and I felt like, you know, a way to keep his memory a part of my memory, a part of my world."

Diesel and his girlfriend, Paloma Jimenez, announced the arrival of Pauline -- their third child together -- on March 16. The two are already parents to Hania Riley Sinclair, 6, and son Vincent Sinclair, 4.
Clearly, Diesel and the rest of the Fast & Furious family are still reeling from Walker's death, particularly as they do promotion for the franchise's latest installment, Furious 7.
"When the tragedy happened, I lost my best friend," Diesel said at an early screening of the film last week. "I lost my brother."
"This was a labor of love," he added. "It was in some ways the hardest movie I ever had to do."
Furious 7 will hit theaters on April 3.
