Dwayne Johnson sang to his newborn daughter Jasmine in an adorable Christmas-themed video he shared via Instagram on Friday, according to US Weekly.

"Twas the night before Christmas," the "San Andreas" actor captioned the holiday video along with the hashtag "#BeCarefulSantaShesTough."

The video shows the 43-year-old actor cradling the newborn in his arms as he sings "Jack Frost nipping at your nose" to his week-old baby girl. "If Santa tries to scare me tonight, I'm gonna kick his a--, daddy," Johnson says, mimicking a baby's voice as the camera pans to little Jasmine, before wishing everyone a Merry Christmas, according to ABC News.

Johnson and girlfriend Lauren Hashian welcomed the little one on Dec. 16. This isn't Johnson's first child, as the actor also has a 14-year-old daughter from his previous marriage to Dany Garcia.

Johnson, also known as "The Rock," gushed about the new baby's arrival in an Instagram post he shared earlier this month.

"Christmas came early! Within minutes of being born she was laying on daddy's chest. And being a grateful man takes on a whole new meaning..." he wrote at the time, as HNGN previously reported. "Thank you guys so much for the awesome congratulatory wishes and love you've been sending @laurenhashianofficial and myself. We're extremely grateful."
