It's a Christmas lullaby!

Dwayne "The Rock" Johnson took to Instagram on Thursday, Dec. 24 to share an adorable video of himself happily serenading his newborn baby girl, Jasmine — and we can't get over how precious the father-daughter moment is!

"'Twas the night before Christmas… #BeCarefulSantaShesTough," the 43-year-old pro-wrestler captioned the clip.

Dwayne and his girlfriend, Lauren Hashian — who started dating in 2007 — first announced they were expecting in September and welcomed their little bundle of joy on Dec. 16. Though this is their first child together, "The Rock" is already a father to a 14-year-old daughter, Simone, with his ex-wife Dany Garcia.
