Dwayne Johnson & Baby: The Rock's Daughter Jasmine Already Cooler Than You!

Besides never getting old, the mark of Dwayne Johnson is how nice a guy he seems to be. So it's no surprise that he's extra cool now that he and girlfriend Lauren Hashian welcomed a baby girl, Jasmine, just ahead of Christmas -- and Instagram shows The Rock wants his newborn daughter to be just as cool and badass as her Daddy!

According to MTV, the San Andreas star took to Instagram on Christmas Day to share a clip of himself singing a carol to baby Jasmine, where he teaches her, in the most adorable way, to kick Jack Frost's butt if he messes with her.

"Jack Frost nipping at your nose," the actor and former wrestler sings to Jasmine, then, acting out her response, sings, "Santa tries to scare me tonight, I'm gonna kick his ass, Daddy."

Johnson is active in social media, and earlier this year he broke the Guinness Record for the most pictures posted in a short amount of time, so it's no surprise he took to sharing the first few days of his daughter's life on Instagram -- or any other medium, really.

As Today reports, baby Jasmine is Johnson's second child. -- he has a 14 year-old daughter, Simone, from a previous marriage. From past interviews, it's clear the tough-looking actor is a softie when it comes to his girls.

On Oprah's Master Class earlier this year, the Rock got emotional talked about his relationship with his oldest daughter and how, when she was a baby, he held her and told her he would always take care of her.

It's too adorable to see such a big tough guy loving his children so much -- and let's hope for more sweetness from the Johnson-Hashian household soon!
