Vin Diesel names baby after Paul Walker in touching tribute to friend and co-star

The Fast and the Furious star Vin Diesel recently welcomed a new baby and revealed today that his new daughter's name holds a special place in his heart.

Diesel and his longtime partner Paloma Jimenez named their little girl Pauline, after Diesel's friend and co-star Paul Walker.

Proud papa Diesel posted a photo of his little bundle of joy to Facebook on March 16 along with lyrics from the Louis Armstrong classic "What a Wonderful World."

The same day, he posted a publicity still of himself and Walker from Furious 7 to Instagram with a caption saying Walker had been with him in spirit that day.

"You would've been proud of your big brother this weekend...Even my mother said you were there in spirit Pablo," it read.

Earlier this month, Diesel became emotional when talking about his friendship with Walker during an advance screening of the movie.

"I lost my best friend," Diesel said. "I lost my brother."
